i've had same problem with generals but now i can play it no problem with 2 networked computers... even with multiple computer controlled teams.. the reason?.. i bought 2 soundcards.. 1 for each comp (audigy 2zs n audigy4) no idea if make has anything to do with it.. i doubt it, but i remember some1 saying if you disable the sound you don't get the mismatch error, so it kinda ties in... Zero Hour now works fine as well.. After a million years i can now play link up!!! what do you mean no one plays it anymore????
