Object reference not set to an instance of an object

Đorđe Božić

Hi everyone,

Why am I getting the "Object reference not set to an instance of an object" when trying to upgrade the TM? Actually, not just when trying to upgrade it, the TM is completely unusable because every time I click on a target segment, I get the same error message, which reappears right after closing its window.
I'm using the newest version of SDL Trados Studio 2021 Freelance.

Here are the Upgrade TM log file and error details:

    UPDATE: I downloaded the 30-day free trial version of Studio 2017, where everything works fine, but I still need a solution for this problem.

    Hello @

    I would first suggest removing the TM from the project  and try running a repair

    https://appstore.sdl.com/language/app/sdltm-repair/298/

    If this doesn't work, try exporting your TM to TMX and then import into a new TM

    Hello, Steven,

    Thanks for the suggestions, but, unfortunately, none of them worked.

    When I try to export the TM, I get the same error.

    Screenshot of Trados Studio export error message stating 'Object reference not set to an instance of an object' during translation memory export.
