system restore catastrophic failure

I have installed Vista Beta 2 and everything is working right except for System Restore, when I launch it from the control panel I receive a message that there is a "catastrophic failure". Any idea the cause?
Pentium 4 3.0 (O/C to 3.4) 1 GB Ram Hard Drive: C: 25.5 GB (Vista), D: 97.7 GB (XP Pro), E: 19.7 GB Data, F: 1.99 GB Data, G: 3.99 GB Data ATI Radeon 9600 128 MB

Yesterday I tried out the System Restore to see if it worked. Previously under XP, System Restore would sometimes work, but most of the time it did not. However, I found that System Restore worked very good in Vista. I messed up an uninstall if VMware Player and even manually deleted the files. When i did the System Restore, everything, including VMware Player was restored and in good order.
