On Trados start-up, error "Index was out of range. Must be non-negative and less than the size of the collection." appears. Trados then closes by itself.

Whenever I start Trados, this is the error that comes up. I hope this logfile will be helpful.

The other threads about this issue seem to happen when Trados is already running. Mine just refuses to start at all.
