I am REALLY new to GC2: dread lords and I love it BUT I have a problem, when I finally figured out how to colonize, I went a little fast and I had like 6-7 planets, I started to go into debt, so I figured I would build trade centers to generate revenue, the queue on the screen though said 'Never' and it wouldn't let me build it, why is it doing that, is there something I have to build first to be able to build factories, farms, etc on a colony, I got out of debt and it was still saying that, I cannot figure it out but it's killing me to buy those places outright, I know this question is crazy basic but I've never played this game HELP!!!!
