DarkRP server Installed a addon now all car and custom playermodel textures are gone!

Hi guys!

My name is Limpbowl and I own a Australian DarkRP server.Everything was going fine on my server I have a workshop.lua in my autorun/server and I added this workshop addon for my server into it: Passenger Mod (fixed) v.1.0 Link here: http://steamcommunity.com/sharedfiles/filedetails/?id=231171943 Now people are telling me they can not see the TDM Cars or Custom player models I installed.I uninstalled it from my server now people still have the problem with the cars and playermodels! If someone could help it would be very much appreciated!

EDIT: I just found out that you can’t post help threads in Gmod General Discussion Sorry! I added this problem also to the Help page.
