I have a fat white xbox 360 with a 120gb hard drive... and recently I've been having problems launching Xbox Live Arcade games. Most recently, I tried launching Castlevania LOS Mirror of Fate HD and it launches for about 5 seconds and then goes back to the dashboard. Has anyone else had this type of problem with any other games. It did this with Serious Sam 3 and A.R.E.S as well. I bought LOS Mirror of Fate and I can't even get to the start screen.
