Yeah, this is a known problem with a fix. The fix is posted in the Known Issues thread in the Supremacy bugs forum, and has been for some time.

Infinite Update Loop
This problem is related to the crash problem above, and actually has the exact same fix. Replace the HttpDownloader.dll file in your main Supremacy folder with This One. Then, click on Start => Run and type "%temp%UAB" (Without the quote marks) in the box that appears and press enter. This will open a folder called UAB; if there are any files or folders present in the UAB folder, delete them all. Run the game and if it says an update is available, let the game download it and restart the game. If it gets stuck in another loop or crashes, please post about it in the Supremacy Bugs forum.

If it doesn't work, let me know. This fix is specifically for XP as well, so it might be a tad different in Vista or 7. By the way, nice to see you posting on the forums again.
