Anyone else got the issue that on trying to launch, they just get a "A severe error has occured"-popup on a black background, and that's it?

From the details given (something in C:\DATA missing) it seems to complain about an incorrect path, but I can't imagine that's intended behavior that it is looking there.

(edit)
Nevermind, has to be run as administrator. Can we get an option for that in GOG Galaxy? :)
