After installing MOHAA, I cannot install Spearhead due to the message "registration number is not correct". I believe this is prior to the normal CD Key prompt. Both games are originals and are part of the Deluxe Edition. MOHAA Breakthrough has the same problem. Any ideas?
I have the same game (I LOVE THIS GAME)I'm sure you put the registration number key on the back of case were it tell's you to..right. The number key is on bottom left corner on the cd case. Try to re-enter the number key again.
