So it's something in the outdoor level then. Maybe one of the files in that level were corrupted on your PC and cause a later crash after it's read. The first thing to do is re-installing: remove the outdoor level and Gamestudio completely, also physically delete their folders, then install it again and let the wizard create the outdoor level again.

Also, download and run the newer demos from the download page to be 100% sure that everything else but the outdoor level runs on your PC.

Let us know if this helped.
