@ XGames, email sales your registration key and we can have it reset.
@dennisb - send me a copy of the game unprotect I will have the team load it with PGPS and we will test it against our Towers. After looking at your site for the game seems like you have alot of custom content, dont think that would be the issue but we know you are using FPSC V1.12, when PGPS was made it was for ver 1.04 - 1.08
Since then we have not had any beta testers to see if the updates may be causing your issues. Have you tried with the version below to see if that is indeed the issue is your version copy?
