Hello everyone,

I used the MultiTerm Termbase Migration Tool to convert my .sdltb termbase files to .ttb format.

The conversion process completed successfully without any errors and the I could open the converted termbase in Trados Studio 2026. However, when I try to open the converted .ttb files in MultiTerm 2026 Desktop, I receive the following error message:

"This termbase cannot be opened because it has been created with an unsupported version of MultiTerm."

I have attached a video below showing the exact error message and the steps leading to it. It seems that MultiTerm 2026 Desktop may need an immediate update to address this issue.
