Save games corrupt from 64 Vista to 64 Win 7?

Hey all, I was playing Arcanum on my Vista 64 bit laptop (patched to 1.0.7.4 and with the high res patch at 1280x1024) and it was playing like a champ. However, when I copy the save game files over to my Win 7 64 bit desktop (also patched with 1.0.7.4 and high res patch at 1280x1024) and try to load that specific save game I get a dialog box saying the save game is corrupted and it crashes to the Windows desktop. Fresh start games that I create on the Win 7 system are playing fine, its when I copy the files over from my Vista system that Arcanum gets pissed.

Any thoughts?

Thanks in advance...
