hey mate had that a while back too. Are you running the 6.5 update? because i had so many problems with it (including the one you mentioned) i decided to go back to the old 6.0 version, which seemed to be fine

It seems to occur at the exe part indeed, however this problem never happened in 6.0, dont know if that would be of help to you?

Also could it be that your textures are too pushy for the engine, i had a 6mb TGA for a skycube which crashed the engine on load every time. Possible that you'll have to scale down textures or reduce their resolution? But im quite new here compared to you guys, so dont take my word for it.
