I bought this on Amazon last evening, and downloaded. Everything installed and I had no trouble with activation.
But, the program starts to load, the music and waves can be heard, it renders about half the screen- so you can see the upper portions of the sails, then it stops and plays music. Hitting ESC closes the program. There is no error generated.
This happens at any resolution, with or without running in windowed mode, with or without detailed textures.
OS is vista home x64
hardware is more than sufficient and passed your computer checker software.
