i dont know to much about this but i have combinrd ops, all units availible for the baf dlc (textures show real spooty and crappy like). After purchasing and installing the baf dlc, i launch Arma2:CO and the game runs slow and the BAF unit model textures still dont look like all the other units. I didnt know if there was a way to merge BAF into Arma2:CO or if i can install the DLC pack and copy/paste the data into the Arma2/Arma2:OA addons folder.

Check your expansions menu, make sure the BAF box is ticked, that should fix the texture issues. Launching from the BAF shortcut should have a similar effect. (I know it sounds like a no-brainer, but you'd be surprised how many people don't try the obvious solution! )

I'm not sure what could be causing the crashes though...

I figured this one out so im posting it for anyone who may have a similar problem. Befor using BAF on Arma:CO you must first start arma2 without Arma:OA and then relaunch Arma:CO. After the first time it worked fine for me but i tried unistalling BAF and then reinstall, launch Arma:CO....same problem, then repeated the same steps to get it to work. I dont know if thats the right solution but it worked fine for me after that.
