I apologize because I'm sure this has been answered before but I couldn't find it by searching. Long time fan of C&C. Played on discs back in the day and now on Origin. But, like many I've have had issues. I've loaded CnC and can now play skirmishes but looking for what I need to do to play the actual missions? As I said, I bought it on Origin. Is there a way to connect my Origin and CnC to be able to also play the original game modules? Thank You for your help!
