Too difficult to answer this one without more information.  Where are you trying to open it... in the Translation Memories View?

 I tried to install "SDLTM Repair" plugin, but it doesn't work.

Why not, what happens?

What version of Studio are you running?

Hello, Paul! Thanks for your answer.

The message that appears in the plugin doesn't specify what happens...

There's no way to open the translation memory, neither with the translation memories view. The same error appears (when creating a project and when trying to open the TM)

I'm using the 2021 version. Hope it helps!

So the plugin did install.  Then you used it, but it didn't help?  Can you share a screenshot of what you see after using it?

ok - in this case reset Studio.  To do this just close Trados Studio and then rename this folder:

c:\Users\%username%\AppData\Roaming\SDL\SDL Trados Studio\Studio16\

to c:\Users\%username%\AppData\Roaming\SDL\SDL Trados Studio\Studio16_old\

If you can't find this folder then you need to unhide your hidden files/folders:

Then restart Trados Studio and see if that helped.

Thank you very much for your help, Paul! I am a bit desperated nou because nothing works and I need to recover that memory. See below my answer:

That's what the plugin shows after selecting the memory and click on "Repair". There's any information that might help because apparently it works.

This message appears when trying to create a new project after following your instructions, so it seems the problem persists.

Thank you again!

Can you open other TMs without any problems?
If yes, this means that the problem is with this specific TM, which seems to be damaged. 

If the repair does not work, I suggest you recreate the TM and import your latest TMX export (+ SDLXLIFFs of what you translated after the export).

Thanks for that information.  The screen for the repair apps suggests that your TM is beyond repair.  You might see this if you run the integrity check... for example this was the result of one I saw before that displayed the same repair complete message but didn't actually fix anything:

If this is the case then the only next option to try and recover the data, as far s I'm aware, is to try and extract the translation units as plain text out of the database table.  This "might" be possible if the TM isn't too badly damaged and the suggested process is here in this thread from a week or so ago:

Failing that, or even instead of that if you have the files, the solution from Walter is a good one.  But if you don't I think it's worth a try.
