[Zope] Version Paradox

Help !! I've inadvertently created a version paradox. I created a version and joined it, then I realized that I did a stupid naming mistake I tried to UNDO the creation of the version. It allowed me to undo the creation of the version, however I was in the version at the time, and now I am stuck in the version and cannot get out. I cannot create a version of the same name and delete it either. I am stuck. HELP !! How can I exit a version that doesn't exist?
