Thanks

Hi... First of all, I want to thank you for the game, but my key is not working... I think that one character in first set is missing, can you verify that the key is correctly posted? I get fallowing error:
"The product code you've entered is not valid. Please double check to see if you've mistyped your key. I, L, and 1 can look alike, as can V and Y, and 0 and O."
