Thanks for the replies guys.
Well, last night I copied a couple of saves to a USB drive and attempted to load them from one of my 360's that doesn't have any expansions. It gave me a message stating something like "some items may be available, do you still want to load?". After clicking yes, the game starts to load and the locks up the xbox.
I tried multiple saves, I copied saves to the hard drive, and I installed the game to the hard drive, but it lock up in the same spot each time.
So, it looks like it should work but for whatever reason is not...I might play around with it a little more tonight.
Regardless, I'm just gonna tell my daughter to pick up the GOTY edition...
