SDL Trados Studio 2017 won't start (The requested data file could not be located)

Hi! I've been using SDL Trados Studio with no problems till today. Now it won't open saying "The requested data file could not be located" (well, the same in Russian in fact) after trying to load translation memory view.

I have SR1 version, re-installing did not help.

I saw that I am not alone with this problem, could anybody help please?

 

Thanks in advance!
