StarForge screws it up so ProEdit ends up deleting the sound files. There's a way to get around it.. bah. Looks like I'll be writing the tutorial for this..

ProEdit Removing Sounds Glitch [Fix]
This is caused when you use StarForge in making your map. StarForge damages the sound files so that ProEdit removes them. There is a way to fix this though it is a bit complicated.
Requirements: WinMPQ
1.) Get your map ready to be protected with ProEdit.
2.) Open the map in WinMPQ
3.) Prepare to scream
- You should see that the names of the sound files have been changed into a bunch of jibberish. You can either change the names of the sounds back MANUALLY.. or you can remove them and re-add them with WinMPQ. If you take them out first, then you need to use WinMPQ to re-compress the .scx file. I'm not even sure how to do that, but I know you can.
4.) Then you're fine to protect. Hopefully.
