How to completely delete VM and save documents

Can someone direct me in how to completely remove a corrupt VM while saving all my data so that I can reinstall a previous version. I was using 5060 and it became corrupt and non responsive. I tried the Uninstall Parallels and then reinstall 4560, but 5060 is still listed in the about Parallels menu. I want to completely remove 506 from my computer while saving all my data, and then reinstall 4560. Thanks in advance.
