As brought to attention on the official forums, there is a potential glitch that could erase all of your hard-earned stats and unlocks. Experiencing this glitch means any XP boost purchase you made will become pointless.  The glitch spans both XBLA and PSN platforms, and may be attributed to switching from the trial to full version of the game. There hasn’t been any word of a fix, but players should be careful when making any in-game purchases for the time being. We’ll keep you posted on any developments in this story.
