Did you extract Opposing Force into the subdirectory: HalfLife/gearbox ?
DJ Speedstar wrote this about a month ago in the old forum and it worked -
1. get full opposing force from 3d shooter legends
2. copy all files to gearbox (not like they said, to force) dir in half life
3. run ym666fix.bat, click enter 2 times, in KeyGen click generate, copy generated key to Enter CD Key, click ok, run opfix.reg
4. from half life dir, run opforup.exe (if u have that v1.1.1.0 patch installed), show half life dir
5. there r 3 ways to start opposing force
a ) do *.bat file in half life dir with line hf -game gearbox, and start game from this file
b ) start game with parametrs hf -game gearbox
c ) start normally half life, go to custom games in menu, choose opposing force, click active, go back to menu and click new game

P.S. Games Support forum is now accessible, sorry about that.
