Ok, world.exe no longer has any problems after I did what both of you suggested, but boot5zones still says:
Cannot find file '***' (or one of its components). Check to ensure the path and filename are correct and that all required libraries are available.
The asterisks standing for the name of the zone I wish to visit. Do I need to type something more than the zone name, like the path for the eq directory?
And thank you all for such quick and useful help, I'm well on my way to getting this wonderful little program working
