Please Help - GarageBand won't launch

Hey there,

I haven't used Garageband in quite a while. It was working fine the last time I did.
Now that I tried lauching it, it won't work anymore. I can't remember doing anything or messing with it. It will initialize and then close immediately.

This is the beginning of the Problem Details that I get:
