Brick_TopAndKennethThe problem with that would be getting it signed by valve so it runs in vac secured mode.
Is the old prec signed?
Any plugins which need to run while you are in a vac secured server need to be signed by valve or they won't load.
Imo you should just talk to the guy who made it in the first place, chances are it only requires it to be tweaked slightly and recompiled.
