Earlier this week I had an issue with a virtual machine, and killed the Windows service that handles the background running of the actual VM. Now, since then, my Parallels has never been the same. It won't load my VMs at normal speed (takes like > 5 mins just to get the first screen, windows setup or start-up)

I have uninstalled and reinstalled Parallels more than a few times, and in between each time, I have run register cleans and also HD Drive checks. I never have to reenter my serial, which means some Parallels setting still remain (even when the Parallels directory is removed in the user's directory and the Windows directory and the program files (x86) directory.

My system is running Windows 7 Professional Edition 64-bit. Before killing the service, Parallels was running great...
Any assistance would be appreciated.
