If you keep resetting the VMware, its unlikely that might be the cause. At any rate, its worth a shot. The folder will be under:
C:\\Docs&Settings\\AllUsers or UserName [depending on install type]\\App Data\\MimarSinan....
I'm really not sure why you'd have any problems at all on a clean machine. We do most of our testing inside VMware ourselves and haven't run into any issues with web media blocks.
I'd ask for your project again
