So, I have gotten into Minecraft mods, and I've been trying to install ModLoader.

The problem is, nothing works. Tried clean install several times, no success, instead crashes. Deleted META-INF all the times, checked the other folders, even moved out all the texturepacks. So, nothing works.

Here's the crash splash:

Minecraft has crashed!

Ah, I used to delete META-INF as a whole, so that's what I've been doing wrong. Derp me. xP

Thanks for the help Cestislife.
