That totally sux! I feel for ya dude. I bet it won't happen again huh?! There's an ol saying you probably know...

Screw me once, Shame on You
Screw me twice?, Shame on me!!

I don't know if you have incomplete files that can be restored, but probably not. I'm not by any means a computer wiz so maybe someone else knows if you can somehow send your incomplete files back into download mode. It would be nice huh!?!

Good Luck!
