Have just started using VMware Player on Linux myself, did run it on Windows a couple of years back.
So far, my luck has been good, the OS's I have installed are Windows 7 & XP Pro, both are running fine. I seen where some users has uninstalled & reinstalled VMware Player, though on Linux this is easier said than done, was lucky to get mine to upgrade to 7.0 from 6.4.
Oh & one thing I almost forgot, Online Armor doesn't play well with all VM software. Have you tried disabling OA & seeing what happens? I have a hunch that may be the key to your issue. Many has reported this.
