I cant get permissions working. I just get 'permission paratrooper.admin doesnt exist'. What am I doing wrong?

That would be because that is not what it is called.
paratroopers.admin there is an "S" in there and you don't have that in what you posted. "paratrooper.admin"

I copied it, so I didnt mess it up ;) But I deleted it, then added it again. That magicly worked the 6th time! Thanks tho :)
