I purchased the game on SE, no I do not have the steam version. I have done the following:

* I went on the code redemption website and entered the code, I tried copy and paste, case sensitivity, and even " - " but nothing worked it kept saying code was invalid.

*I tried entering it manually and even had my girlfriend give it a try and it did not work.

I am not sure what else to do, I cant redeem the game or get an early access code, has anyone else experienced this and if so how did you resolve the problem?
