Before downgrading, try to reinstall Parallels Tools in the guest OS.
Uninstalling Parallels doesn't mess inside your virtual machines.
If you're so inclined to eliminate it (thou I think the problem is that you did not upgrade Parallels Tools inside your Virtual Machine. Yes, you have to, with a new version comes new drivers) just uninstall the the app the usual way and don't eliminate your settings or erase your virtual machines. And then you can install the old version, thou you'll probably have the same problems since the current Parallels Tools you have might have been disabled because they were rendered incompatible, so you'll have to reinstall those either way *snicker*.
