I had some problems as well, but I've been able to solve them.
My installation stopped at %, so I manually installed the game and did everything that was explained above my post.
However, the game crashed back to desktop after loading about one third. I looked into the error.log and it said it couldn't open the 'objects-something' file in the static-map.
Here's what I did. I checked the static-map, and saw that all files were set to read-only, since I copied them directly from the cd. So now I only had to uncheck read-only, and BING!! The game works <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
Hope it helps some of you people too!
