Trados 2007-Could not contact activation server

Dear all

 

I had to restore my computer OS with an old backup. Since then I've had problems with Trados 2007 license.

I use the "License Manager" : First I saw that my license was tagged as "damaged". I repaired it and it was OK.

Now Trados cannot find my license again (don't know why) and I cannot activate it online. When I do this I receive the following error : "COULD NOT CONTACT ACTIVATION SERVER (ERROR CODE 0)"

Could someone help me ?

 

Thanks a lot,

Olivier
