I have an issue when running visual munge when trying to make a world.
It is my first time using it so please help.
When i hit the button to "munge" after making the name and description it begins to create the world, but it soon stops with a runtime error. please help.

Looks like something got corrupted when you downloaded the file. What I'd suggest is: First uninstall it and install it again (this does NOT mean download it) and then if that doesn't work try redownloading. I'm pretty sure it's a error with corrupted files, but I'm sorry if I'm wrong.

What operating system are you using? Do you have enough free hard drive space?

I use XP Home edition in 32-bit and ive got plenty of hard drive space.
