Alright i have had this game for a while and i just never had a good computer to run it on so i never opened it till today.      this morning i downloaded it and created an account with ironclade so i could play online, then it said i was playing the old version of sins of solar empire.. so i went to update with impulse i have to create another account there.

then i clicked on update a small pop up page cam up i entered my CD code my email and the rest of the stuff but when i press (OK) it says Product registration failed:the e mail address or serial number u entered is invalid check to make sure you have enter the correct information. well i checked and i did enter the correct information so i am wonder what the hell is wrong ??.
