Recovering Dead Apps After Syncing

[iMule]

I downloaded Windows 7 and due to my hate of Vista, I've been primarily using Windows 7 because it allows me to take advantage of my soundcard for recording my guitar directly through line-in and it also allows me to listen with ASIO. So anyways, I was sick of all my songs, and added completely different songs in Windows 7 through a sync. The problem was that I didn't log into my account and my applications apparently weren't synced correctly, because they're all dead (meaning the initial interface pops up for a second and then shuts down unexpectedly). What really sucks is that I record lectures in one of my classes on the Recorder app. I have most of them, but since she reads test questions out randomly, I can't retrieve the last two recordings. Nothing seems to be working. I hate jailbreaking, but if it comes down to it, I might have to use SSH. Is there any other way I can recover this data? I have no backup either. I'm backing up now, just to experiment. I have almost a gig of apps that's still showing in itunes also, so I know it's still there.
