Heya... sorry my first post comes with a problem...

I just bought TOW from Gamestop on the sale...

It downloaded and installed fine... it brings up the Serial Number popup... and I type in the provided product code provided by Gamestop... and what happens is the popup re-pops after entering the code and its blank... I tried ctrl-v pasting and the same thing, I cant get past the SN popup... can someone possibly help me?
