Art, I had this same identical problem, and found that it was caused by installing Akeeba backup with the 'rollback' plugin active. If you've already installed Akeeba, try disabling the plugin and reinstall VM, but you might want to consider starting from scratch, just to be sure.
On an aside, I'll say it before someone else does. Try using the search feature. My comments on this issue are contained in a thread with the virtually identical title only nine posts down.
