With the latest VPinmame4, I began to have the very same problems you have. At first, 2 current games don't work but the rest does. Then 2 weeks later ALL games end up not working. The error message mentioned cannot find the VBS files even though it's in the tables directory. From my pc environment:
My pc environment:
1.7 GHZ pentium
256MB RDRAM
WinMe
MS IE 6.0
VPinMame10b1
VBS221
VP beta4

The solution for my case was to go back to an earlier version of these two files:
MS IE6.0 -revert back to - MS IE5.5
Visual Basic script (latest) - revert back to - VB SCRIPT 5.5
After that, the OLDER tables work again, that is most of the Vpinmame tables (except for SafeCraker and Addams Family 3.0 or later).

Hope that help. It did for me. Thanks to Apocalypse and Joe.
