iPad get stucks on Step 2 (Back up) of sync

Hey guys, I have an iPad 2 and every time I've tried to sync this morning, it's gotten stuck on the Back Up portion of my sync. I've tried deleting previous back ups under Preferences<Devices. I've also tried restarting the computer/iPad... Things just aren't working out. Anyone have this problem before?

I'm running iTunes 10.7 and was able to already successfully sync this iPad on 10.7 previously. For some reason, it's just not working today. Also, I'm running 10.8.2 on my iMac.
