Termbase creation from within Trados Studio 2019 fails with error "MultiTerm is unable to create the termbase. Not a valid file name."

Hi,

Every time I try to create a Termbase, this fails with the above message ("MultiTerm is unable to create the termbase. Not a valid file name").

I have really tried everything: I have followed all the advice in every thread I have found, but to no avail. I have also tried to create the Termbase both from within Trados and with the Trados 2019 Multiterm Desktop app.

Since I have seen quite a lot of people reporting this issue, I would imagine this is something that, for some reason, Trados is prone to develop.

Please HELP! This is driving me insane.

Thank you very much.

Sergio
