Can't install BTW 4.16 without MCPatcher

[dragon3d]

When I start with a clean copy of minecraft.jar, install Modloader and BTW 4.16 the traditional way (deleted META-INF and made sure there wasn't anything in the mods folder) I get this error:

However, if I use MCPatcher it works. I unchecked all the other features MCPatcher offers and only added Risugami's Modloader and BTW 4.16.
I don't know why MCPatcher makes a difference since I am using the same files. I only tried MCPatcher on a lark earlier when I wanted to see if Optifine helped me with FPS, now it seems like the only thing that works.

Your crash log there says that only ModLoader is installed. What exact steps did you take to add BTW to the jar?

This sounds like your zip programm is messing things up and also explains why MCPatcher works without a problem.
Try using 7zip, it hasn't failed me yet in the hundreds of times I edited my jar.

I am just dragging the files into the JAR file (using 7zip), first Modloader than BTW. After I posted I started to think maybe there was some residual file left behind by some previous version where I used MCPatcher. But I thought that deleting the /bin folder and re-logging in (to download a fresh JAR file) would clean and/or disconnect any old config files. I also tried just installing Modloader and it started up fine. It only crashed when I added the files from BTW.

I've been playing and adding mods to Minecraft (including occasionally BTW) since Beta 1.5_01 so this has me baffled. I suppose this stands as a warning to anyone who uses MCPatcher... It works for now, but next time I will be deleting the entire .minecraft folder to see if that helps.
