Return of Reckoning

I quit the game a while ago, because the RoRLauncher just stopped working entirely one day, it won't even start at all. I tried several solutions, that were offered to similiar problems on the forum, but it still is no use. I have no idea, what to do, since there isn't even a log, or error report. I had tried replacing the game files before, the launcher itself, running it as an admin, but the issue remained the same, and still persists now. It appears for a brief moment in the Task-Manager, along with a Windows Problem Reporting application, but they both disappear after about three seconds. The JeFawks Launcher does the same.

Help would be very appreciated!
