I still need help people!
You sure do, you forgeted your important add-ons up, and I have no idea what other possible damage you might have done (did you delete the Rocket L or the Sword too by any chance?). All for the sake of a crappy broken add-on, downloaded add-ons are NOT supposed to overwrite existing datablocks of other add-ons. That thing is grounds to be fail-binned.
You're going to have to go around and read the actual Add-on rules before you even start making any, that's where you should start. You'll learn a good few things that way at-least, just don't expect to be "pro" within a day or something.
