USB Issues TP2 Windows7 back to Xp

[DownNeverOut]

First any assistance is appreciated.....

usb not syncing, will charge only. Running JuicyRom.R6
I've uninstalled Active Sync, hard reset, read throughout the forum and haven't discovered the answer. Finally attempted to flash via SD.....NO Luck. Card is Fat32 formatted, found .nbh renamed it nada.....Help!!!! I can't flash, can't sync, and want to bring phone in due to serious battery drainage. And I believe all my problems began after syncing to Windows 7. Went back to Xp, and now I'm @#%%^^. HELP PPC'ers
