"General massive catastrophic system failure" error message when adding termbases

Hi!

I use Trados Studio 2015, SR2. 

A few days ago, I started having problems adding termbases. Whenever I try to add a termbase to a project or open a project with an existing termbase (or try to create a new project based on an old project that used termbases), I get the following error message:

General massive catastrophic system failure

This error only started manifesting itself a few days ago. My termbases are located on another drive, if that gives you any clues. I had problems with termbases when I first installed SR2, but these issues were later resolved thanks to the wonderful Paul Filkin. This is clearly a new problem, as the error message is different.

I would be grateful for your help, as I rely heavily on my termbases.

Kind regards,

Johanna
