iTunes/iPod Sync Error

I have used Windows 7 since the first beta release and I have explored nearly all of the different builds. However I still find the same error occuring. I have having troubles syncing my iPod. I never used to get this error with Vista, it has only been with all of the Windows 7 editions.

I'm currently running Windows 7 RC 64-Bit and the latest iTunes 64-Bit version.

The problem is that When I sync my iPod, the capacity bar located at the bottom of the screen turns all orange and states that I do not have enough room on my iPod.

Where in fact I do, my music is a mere 2GB and my iPod holds 4GB.

I have included a picture of the problem occurring, and I hope that you guys can help me solve the issue. [attachment]

NOTE: I have tried using Windows Vista compatibility mode, and the error still persists.

I can manually add songs, however I never have this problem whilest running Windows Vista a week ago. I have only had the problem with Windows 7 (both the client I'm using and the client beta).
