I have owned and played this game since it first came out and never a problem, untill now. Windows 7 became so unstable I had to fdisk and start over from scratch.
Problem is when I play a game, my starbases don't get all the options I research. When I research Starbase Fortification I, none of the modules are available to any of my starbases. When I research Fortifications 2, the weapons modules for fortifications 2 become available but still no defenses.
