Hey everyone. I am new here...I have DL the client and I am able to play online or skirmishes just fine. my issue is I can not play the missions (the game keeps crashing) when i use the old RA2/Yuri path. The C&C.net path does not give the option for the missions. is there a repair patch that will allow me to play the missions? All my C&C games come from Origin if this matters. thanks Scally..
