thanks all, I played the first mssions on the 3rd mission you are rquired to produce laser lynx, I completed all the other objectives the only outstanding was to produce the lynx, again in the colony missions I was unable to produce any fighting vehicle, Convecs etc no prob but anything with a weapon no joy.
I used revolver to open the sheets vol and found the weapons folder empty with a 0kb size So I asume that as this is missing the game will not allow me to progress? I downloaded all the versions with the same result no weapons file every thing else is fine, I never had this problem when I last played the game I use windows 7 with norton antivirus
