I started playing subspace some days ago and I had the endless loop problem in which the game process opens/closes continuosly without starting effectively. I have zonealarm+ad-aware and I haven't any trojans/worms. I found that if I start the game after my computer has been connected to the internet for a long time, it won't start, but if I reboot and start continuum just when I establish my internet connection, it always works without problems. hope it helps ,-) -Nightshade-
