DarkRP entities?!

On my server with DarkRP, when ever I use the entities in the F4 menu (like being a Cook and spawning a bannana) (or even a gun) it wont let me use it. When it spawns in front of me, I hit E and it stays there and it wont let me use it, the item sill stay and the remover toll wont get rid of it either. Why cant I use DarkRP entities?

You don’t have CSS content installed in your server correctly, or else that’s what it sounds like.

Why when I run a bat file to install it, it doesnt work? It just comes up a second then goes away? ?? ??

Nevermind. I figured out why (wrong directory).
