I was trying to get a server set up to play with some friends and was installing the mods we were going to use (Equivalent Exchange, Mystcraft)

However, I ran into this error log:

Minecraft has stopped running because it encountered a problem.

I removed every mod except Forge and It still showed up.

I am using MagicLauncher v.0.9.8

Can I get any help?

Where did you get my timer mod from?

And where did you install it to?

it sounds that he installed it with a zip and not in the .jar

@Lexmanos Thing is, I didn't. I have no clue where I got the timer mod and I never downloaded anything of the sort.

@TIO2 That's how Magic Launcher Works, I tried installing into the jar, same problem.

Ya.. clean up your minecraft folder, looks like you have shit in there you dont know you have.

Ahh... Found the Issue! Thanks for the help LexManos!
