Hello Manuel Huygen ,

This issue sounds exactly the same as what was discussed here (with solution)

https://community.sdl.com/product-groups/translationproductivity/f/studio/9992/invalid-character-in-the-given-encoding-line-1-position-25

Hello Steven,

Thank you very much for your help.

In fact it's not exactly the same problem: in the case of Geoffrey, his TBs came from another software, while mine come from Trados Studio. As a result, I don't have XML files at my disposal, like Geoffrey, so I cannot progress the same way.

Best regards,

Manuel

Hello Manuel Huygen ,

All SDL TB's are the exact same format- SDLTB and these are always managed via MultiTerm  even though you are working in Studio.

Please log a support ticket via your SDL account/ Support/Licensing and Installation and our support team can take a look for you and should be able to advise you if this is a bug/installation issue or not.

Hello Steven,

Thanks for your answer and your advice, I think it's the best way to try to manage this problem, indeed,

I will log a support ticket.

Best regards,

Manuel

I finally managed to solve the problem.

Because SDL FreshStart told me "Multiterm is currently running", I did CTRL+ALT+DEL

to access the task manager and realized that in fact it was Multiterm Widget that was active (!).

So I just stopped the Multiterm Widget, and manage with SDL FreshStart to regain access to my TBs.

At last !
