When I start to play SINS ill go to the Ironclad Online menu to set up my account for online play. I click create new account and enter my desired account name and password then I type in my cd key which I found on a sticker located above my game disc inside the box. I tried many different combinations of the game key making sure that I didnt mistake a O for a zero or anything like that but whenever I clicked create account a box will pop up saying wrong version of Ironclad online d

If it helps any, I only have half the RAM required and a 1.2 GHz Processor. Is that the reason its not working?

So I downloaded sins and it said it was successful, then I go to play the game, the screen goes black, and nothing happens. Now I dont know the exact requirements of my computer but I thought it could handle this seeing how it plays world of warcraft and similar games. Im not exactly sure if those are even close graghics wise though haha. Can anyone give me some advice on what may be happening?
