I just purchased the game Siege of Avalon, AWESOME! But, In the middle of Chapter 1, it locks up and when you reboot your computer and get back into it, colors are all messed up, patches of walls missing, etc. have to re-install to fix. Now what I purchased was all 6 chapters, the anthology, the latest I guess. I can't find the company, the websites are gone, everything. Even the publisher, Global Star Software, doesn't know anything. HELP!
