I used to play this game extensively as a kid, and I absolutely loved getting to play it again. Previously, I played on Vista 64-bit, then installed 7 64-bit and now performance is terrible and the screen won't display correctly. After repeated submissions to GoG.com support, three weeks later I received an email that was absolutely no help. I replied to said email with even more detail, and still no help from GoG.com. I don't think I will be making any more purchases from GoG.com if they provide this atrocious level of support.
