I just built a brand new HTPC with i3/GA-H55M-S2H/Windows 7, and a fresh install of XBMC. When I first installed XBMC I got an error saying that "XBMC could not start". After searching google, some people said to launch it in portable mode, and that takes care of it. So I tried that, and now XBMC just launches to a black screen and doesn't do anything after that. Has anyone had this problem and what did you do to solve it?
