The screw-up you were talking about is maybe you accidently clicked it and launched it. If you are playing on line, contact the westwood solutions page. You may have to get an update of the game. Any more questions, contact me, benwtkns212, via private message.
UMP is essentially a mod - it will prevent games saved without the same version of the UMP loading properly.
As for the Rock Patch not recognizing that tmapm has YR 1.001 - it's probably because of missing registry entries. You'll need to reinstall YR (or apply the registry entries yourself). I don't know why people complain about this so much because if you try to run YR without registry entries you get the 'everything explodes' issues. So I reason there's no harm using the YR registry entries for my installation programs.
