I'm new here, so excuse me if this is a stupid question.

Anyways, yesterday I downloaded the World of Minecraft Custom Client, and it was working fine. I built an awesome map, and I saved it as a .mine file. The problem is, now that I try to load the file again, it doesn't work. I pick the file on the load save menu, and it just goes back to the newly generated world. Am I supposed to somehow pick my save before I press 'Go!' in the beginning?

Thanks in advance!
