Error: L'entrée n'est pas une chaîne Base 64 valide, car elle contient un caractère non-Base 64, plus de deux caractères de remplissage ou un caractère non conforme parmi les caractères de remplissage

Jimi Brice

Hello,

SDL Trados Studio 2021 was working fine on Saturday

When I launched it yesterday however, it just gave me this error message (in French) : L'entrée n'est pas une chaîne Base 64 valide, car elle contient un caractère non-Base 64, plus de deux caractères de remplissage ou un caractère non conforme parmi les caractères de remplissage.

Then wherever I click the software closes so I can't do anything.

I have a student account.

I tried putting my translation projet in another location so that the software launches without taking it into account
I tried repairing Trados
And I tried uninstalling Trados then installing it again, to no avail.

I don't know what else I could do...

Here is the error report:

    Hello! Problem solved, thank you!

    I think it is subscription based, but how do I know? I received my license from the university.

    The first link didn't help but the second one did help to solve the problem! And my master's thesis project appears to be intact!

    Thank you very much!
