UPDATE:

I did infact get a secondary email this morning. It was located in my spam folder. which is odd...cause all my other emails from square and digital river are allowed and came to my inbox.

If you still dont have your second code....check spam folder.

When you get it..Sign into mogstation and ADD SERVICE! DO NOT HIT ADD ACCOUNT!
Hitting add service for either PS3 or PC. then it will ask for new code. input, and BAM...your good to go.
