Help with deth level editor

I need help installing DETH on my computer. I unzip it and the folder comes up showing the DETH files. When I double-click the DETH.EXE file it goes through all the copyrights info and shows an error message at the bottom that tells me that the path to the Doom2.wad couldn't be found. I need help figuring out how to get DETH to find the path to the Doom wad files on the disk for my Doom games. Any help would be appreciated.

Edit DOOM2.CFG

I don't think that's going to be your last question (ducks)<g>

Okay, would that file be the Doom 2 file in the DETH folder? How do I edit it? I've got tons of maps I want to make!

.cfg files are usually easily edited with Notepad, Wordpad or DOS Edit. And, most of those that come with Doom editors tend to be very easy to figure out, too.

I've got it to work! But now I have another problem, when I go to play my maps they won't load. The configuration screen will come up (the one asking you to choose a level and everything) and I'll select one of my maps to play. Then the Doom95 screen will come up and load, after a while a message will come up saying that there was an error, it said: Bad Music Error 125. I need help, I want to play my maps.
