I got IP last night and downloaded and played it. Than I went to try to redeem my stuff for a pre-order, and I was successful on 2 out of 3 things. The last one says I need to register IP, do I want to do that now? I click yes, enter the serial number sent to me in the e-mail, and it says the code is invalid. I really want to register because having that grayed out icon on my sims3 page is driving me crazy, especially since I DO own it. What can I do to solve this?
