I set up my account earlier for my PC, and I checked the e-mail I thought I added to this account did not show up for the online gaming. I was wondering if I could change my e-mail on the account so that I can get an e-mail for that code? Or do I have to wait for gamesas.com to send me another e-mail with a different code to the same e-mail address?

I dont understand what you mean, to play online, you just add the codes when you start up C2
