Split post brings up error page

[creations]

For moderating purposes.  I tried to split the last post from a thread to move to another board but got an error page. Tried a few times, same thing.

Glitch? Solvable?

not sure.  can you post what you were trying to split, so I can try too?

Sure.  It was this thread on EASY. It's no longer the last post as both myself and OP have posted to it since. I tried to split from #6 before we both posted there.  Poster is starting a new thread as I couldn't split.

When I clicked split it looked fine and I got the usual question with drop down about how much to split but after choosing "this post only" (or whatever it says) it went to error page.

This is the error I got:

Duplicate entry '0-41' for key 'firstMessage'

Note: It appears that your database may require an upgrade. Your forum's files are currently at version SMF 2.0.8, while your database is at version 2.0.2. The above error might possibly go away if you execute the latest version of upgrade.php.

Definitely an Andy/Tom issue.  Wish I could help.
