Version problems from Steam and PBW Updates

[Randallw]

Is this one of my games?

I already have BM 1.09a, or at least 2 files soemone sent me that seemed to do the trick.

I have 2 versions. Up to date and previous version. Until now it was a simple matter of just of just updating the older one, but the recent patch messed things up by upgrading my most recent version. I ended up having to delete the old version, reinstall, and an old patch worked on that one. I assume it set the registery to the newly installed copy.
