Dan, first, backup your Data.fs.
Second, I only can repeat something out of my memory, cause I don't have 
access to a zope ATM. But I see several things you can do:

- In the control panel, there's also the possibility to save/discard 
versions, take a look there.
- You can always (re-)create a version you need, because zope identifies 
versions only from their path, so recreating the a version with the 
right idea might be a possibility.
- Entering version just means sending the right cookie, so you can write 
your own method which sends the cookie in order to enter that version.
So, maybe entering that version and doing copy&paste might be a last resort.
- Maybe importing/exporting might be possible, though I don't know if 
(how) it's possible to export versioned data.
