I have some more information to come with.
The application crashes only when trying to add software to the drive. Steam games runs without problems.
I then tried to load in a Counter-Strike:Source and Skype, which resulted in a crash. When I started Dimmdrive again, Counter-Strike:Source was removed from the list of games.
I then reinstalled the software, with no luck. The game is still gone from the list. Another problem I see, is that it's not possible to add software to the drive by dragging icons directly from desktop. Right click and add is the only option.
Hope this helps, and that someone may have a solution.
