I dont really know why that is, but I would try; 1) rename evoxdash.xbe to xboxdash.xbe on C: 2) Flash to 4976.02 3) snap your matrix inhalf and get an x2lite/pro
4) check your evox.ini ? 5) try a different dashboard if worst comes to worst 6) make 100% sure the matrix is properly in place via original dashboard (looking at the bios in settings or wherever it is).
*shrug* I dont really know, just some stuff to try. Im sure someone will post an intelligent fix for your problem, but for now, at least you have some stuff to try?
