That story sounds familiar :)
Me and some other guys have been trying to get acre working yesterday, and for most of us it works, but for one of the guys it doesn't work at all. We've tried reinstalling cba, acre, jayarma2lib, ts3, tried all kinds of starting flags (-mod=...).
Basically he has installed OA, and then installed arma 2 to the same directory, to get a combined operations configuration.
We're not using ace, just CBA, jayarma2lib and acre. The acre plugin is activated in ts3.
The only time we managed to get it to work was in arma 2, and it only worked once, after that it didn't seem to work anymore.
For all the others it works fine in arma 2, oa and combined operations ...
Any help would be appreciated...
What versions of the game are you guys using, and what mods (and in what order, don't know if this is important)...
