Printing is possible only using the PDF button:

The Pdf files do not open, I get a blank page

You meet the following symptom: the page "Please wait..." appears, then is replaced by a blank page.

Acrobat Reader actually DOES NOT START: it is not a BLANK PDF but a BLANK PAGE.

However, the PDF has been correctly generated. To save it, you have several possibilities:

  1. Click on the "File" button > "Save as..."
  2. Or click on Ctrl + S.

The subsequent versions to 6.0 of Acrobat Reader are compatible with our PDF generating system. However, in order to avoid or solve this problem, we suggest you to install or reinstall the latest version of Acrobat Reader.

  1. Download the latest version of Acrobat Reader from the Adobe website:
  2. Close your Web browser (Edge, Chrome, Firefox, Safari, ...)
  3. Deinstall Acrobat Reader
  4. Reinstall Acrobat Reader.

Issue when collecting emails with Outlook

While you are collecting emails, you get an error message from Microsoft Outlook. The problem occurs because, by default, Outlook does not recognise the comma that separates the addresses.

Follow these steps to configure Outlook so that it recognises the comma as a valid email address separator:

  1. On the Tools menu, click on Options
  2. Click on Email Options, and then click on Advanced Email Options
  3. Under When sending a message, click to select the Allow comma as address separator check box.

Note: You can use a semi-colon (;) to separate email addresses when you click to select the Allow comma as address separator check box.

My access does not work. The message "A new session has been allocated to a user logged in with your username and password" pops up during your connection

The work session (related to your username and your password) is personal and limited in time.

If this message pops up during your connection, there might be two reasons:

  1. Another user (or yourself on another window) is connecting with your access code (username/password). This ends up closing automatically your work session
  2. Your activation time is up, which can occur after a long period of inactivity.

In order to solve this problem, log in again, a new session will be allocated to you.

My access does not work. The message "Ending your work session" pops up directly after connecting

The work session (related to your username and your password) is personal and limited in time.

If this message pops up as soon as you have connected, check that the date and time of your computer are correct.

If not, you have to modify the date and time of your computer by double-clicking on the time displayed below on the right of your screen.

When I am starting a search, I have to wait before getting the result. Is this normal?

Despite all the precautions that we take in order to maximise the speed of our website, it is always possible that you might have to wait after starting a search. A series of parameters can be out of our control and can unwillingly slow down our information. There are many possible causes for this problem.

For instance:

  • The performances and configuration of your computer
  • Your type of access to the Internet. We recommend you to choose a DSL broadband access, cable, digital leased lines... rather than a simple phone or ISDN access
  • The performances of your Internet provider. You should know that a free access to the Internet will not be as efficient as an access you are paying for
  • The obstruction of the hosts of your Internet provider, but also other providers and/or telecom operators through which your information passes. Etc.

If you identify an abnormal and persistent slow down while searching, please let us know via the email address:, our specialists will help you as far as possible.

My username and/or my password do(es) not work. What am I supposed to do?

Double check that you have logged in with the username and/or password that were provided to you. We draw your attention to the fact that a capital letter does not correspond to the same small letter. For instance, the username "Codata" is different from the username "codata". Besides, check the numeric keyboard, the function "Num Lock" must be activated. If you are using a laptop, do not forget to press "shift" in order to select the numbers on your keyboard.

If your username and/or password is/are still not accepted despite these recommendations, feel free to contact us via

I have lost my username and/or password. What am I supposed to do?

If you lose your username and/or password, send us an email at precising what you need. We will send it to you by email as soon as possible.
