svn commit is failing

Hello,

I need to checkout a previous version of a file to unbreak some changes.
So, I did a co by revision number (the previous revision). That didn't
work, so I did the same with for the next previous revision. I run svn
status, and that file had an 'MM' as the flags. I could check it in, so I
'revert'ed twice, copied my current file over the reverted changes, and
attempted to check it back in. Here's the error I'm getting:

svn failed: The version resource does not correspond to the resource
within the transaction. Either the requested version resource is out of
date (needs to be updated), or the requested version resource is newer
than the transaction root (restart the commit).

Is there any recovery here?
