I'm using catching codes, so most errors should show an actuall error like "Sorry something went wrong!"
Try updating netframework http://www.microsoft.com/download/en..._121LSUS007996
and download the new exe from sourceforge.
Well it seems it hasn't update anything. I still got error by net 4.0 and no folder changeable. "
Just reread, yeah it wont auto update if a error occurs, so just update the exe from the site and it should be fine.
