I have 2 problems actually...

 First of all, I have Gal Civ II DL, Gold Edition with the DA expansion (for which I never see anything on any boards) which, generally, works fairly well aside from occasional freezes during Autosave, which I can live through but what really burns my bacon is that, after all the time it takes to build logistics, once I get between 15-25 points built up, my logistics drops to zero, after which, no matter if I get the Hyperion tech, further research logistics or whatever, I can never create another fleet.  What can I do about this since my opponents are creating fleets and using only single ships I don't stand a chance of defeating them?

In a completely different problem, when I first loaded the game and started it, I was able to replace any major race (while in the startup screens) that was selected for me, with any other race that I preferred.  I could also add more or remove some as I saw fit.  Since that first time, however, whenever I get to the appropriate screen, I see however many major races I selected but I'm not able to switch them out with others or to add more.  How can I change this?
