VladimirTodd / DarkRP-Problems--texture-commands-

Ok, so my buddy and I just got a server to make it a RP server, the problem is after countless hours of getting the gamemode to finally work we face 2 other problems 1 being texture when you press the DarkRP interface (the F4 thing) it turns all pink(purple) and black checkerboard which means "Missing Textre" I have done some homework on websites but, not one could give me an answer! So if someone knows how to fix the texture problem that would be wonderful!!! Next would have to be commands (we use Xenon 24-7 server hosting) who has the commnd !xgui and !noclip stuff like that ok, so when we try to do !noclip it does not work we also can't change jobs. So if you could help us on this one again be wonderful.
