iPod Touch 2G won't sync to iTunes- "required file not found"?

[ghostlyorb]

I did jailbrake with Spirit... and everything was working just fine. I got a cracked version of both Wi-fi sync and Mywi (I know it's only for iPhone).. and now I can't sync to iTunes (neither wired or wireless). any suggestions?

Note: I did post this in the "iPod Touch hack" page.. but I added it here just in case no one saw it on the other page.
