Ah, he just gave me the level file and I tried this, it refused to load with another error, this time indicating something was wrong with the .lvl itself. I took a look inside the .lvl and, well, with Notepad++ it said that there was only one line of text in the level, and that line just said NULNULNULNULNUL... yeah, you get the idea. Obviously something had happened to corrupt the level itself.
On another note, PlatGenWohl is actually a lot better of an editor than I was expecting, I might start using it more.
