Ok, I tried the 6.31.4, 6.2, 6.22 and the bin files don't work, I guess it is my computer. The whole acknex program doesn't work, I have downloaded some demos made with the 3DGS A6 and they just crash just like acknex.exe, I have installed OggDS0994.exe, got the latest directX 9c and it still doesn't work. If you have any sugestions please voice them here. I have Windows XP Service pack 2.
