I figured it out guys!!! The issue with 1.0 players not being able to register codes.
Here's the problem 1.0 players are having with registering codes they bought for the windows version and only the add ps3 service is available.

I knew I remembered seeing this a while ago, 1.0 players should not have bought a windows version because they are not allowed to register another one onto the same 1.0 account. They told us this a while ago and it seems like everyone forgot.
