Just paid for demigod, cant register it now in impulse.
every time i try submitting the serial number (correctly entered, copied and pasted from the receipt page) and the correct email address it pops up an error message :
Product Registration Failed: The email address or serial number you entered is invalid. Check to make sure that you have entered the correct information. (ref: 204)
this is the 1st time i have used impulse, so far even steams 1st release was more reliable. if there is no solution to this then i guess i will be asking for a refund.
