Hey Kris,
This very isolates that its with the application. Was this an upgrade from the previous version? Try manually uninstalling Fusion : VMware KB: Manually uninstalling VMware Fusion
-Once uninstalled, run repair disk permissions. Open Finder >Applications >Utilities >Disk Utility >Select your Mac hard drive >Click on repair disk permissions.
-Restart the Mac and install Fusion.
Hope this helps,
Kumar
