Unexpected Application Error

I hope this didn't have to happen because I'm having a blast so far :(

I received an Unexpected Application Error window in Export mode when loading a new track. RB has crashed. I reopened RB again and saw that it continued where I left off at (I was in the middle of doing My Tags). I am in one player (simple player) mode, the third icon beside the master volume fader.
