When I press Start & Back together ingame (which seems to be the community accepted standard) I get an on-screen message stating that a screenshot has been taken, instead of the menu to whatever trainer I installed. The trainer I first encountered this with is http://www.360haven.com/forums/showt...ht=mass+effect
Which i'll concede is rather old.
That specific trainer seems to initialize fine (I get the custom message upon booting the game) but than when ingame, the screenshot function gets in the way.
Finally, I'm on the latest (last?) Aurora and dashboard stuff.
