I bought Sins Rebellion nearly a year ago, and to my delight, the Galaxy Forge tool that came with it worked like a charm.
Anyhow, after playing with it for a bit, and seeing how thin the multiplayer community was at the time (120 players on at any given time), I shelved Rebellion.
But it always itched.
Finally, after convincing two of my friends to buy Rebellion last night, we got in some good 4x time. However, they kept getting stomped due to our starting positioning being very separate from each other, and they were unable to cope. I recalled that I could create maps with both locked in starting positions and easy-to-control chokepoints with Galaxy Forge.
Unfortunately, my dreams were wrecked by:

I've tried Googling the problem. I've uninstalled and reinstalled Sins Rebellion. I've had Steam verify the integrity of the files.
I've downloaded the newest Microsoft .Net Framework client, and had it reinstall its things on my computer.
Please help.
