I've just installed Rikmuld's Camping Mod, and when I try to launch Minecraft, FML suffers a fatal error.

 

Here's the log:

What did you use to install that mod?

It looks like it's 'Automatic installer' is broken.

Use it's jar directly.

Ah, OK. I used an autoinstaller for the camping mod. I'll try installing it manually and report back.
