Reinstalling the games again and I got to the Opposing Fronts game. Looking over the list of patch releases, I can't find the one that goes from 2100 to 2101. I have the 140 to 2101, but I had done everything in increments as before.
I did not try to install 171 to 2101 before the installation of Opposing Fronts though (which is probably my error). Possibly for fear it would just reset me back to the stock patch that OF is and then I'd be right back where I am
I've done this all before with no problems, its just been so long ago I can't remember.
Anyway, barring a complete uninstall and reinstall, I think that's all I need, the very patch that follows the OF install.
Edit: gonna try the torrent of one of 'em first
