Di you uninstall first before reinstalling?
I only had something like this happen when I forgot to uninstall before installing a later version. (that was a TGC version though, not STEAM)
Back up projects first, then uninstall, then reinstall.
If that doesn't work, then I don't know what to tell you, unless something (or someone) has changed permissions on that folder.
