After about 4 hours of trying to get my boxed C&C generals to work with origin by contacting EA support, I have no luck. My game was purchased at a local store (new) awhile ago, and now i cant use it with origin like i wanted to (so i wouldn't have to use 4 discs). My Game serial doesn't work because "apparently" they don't have my CD key for C&C generals in the database BUUTTT they have my C&C Generals Zero hour code in the data base, i cant add it to origin because you need the base game. And i know the codes worked, i had used both of them before on my old laptop to play online. well im kinda disappointed...
