Map isn't changing.

Hey, so I’ve ran a sandbox server for about 3 months now and my users and I wanted a change. We decided to change the gamemode to CityRPG, you can find that here: http://www.garrysmod.org/downloads/?a=view&id=127879
I put the gamemode and maps on the server and then restarted the server, after that I tried to use ULX to load the map and gamemodel; the gamemode wasn’t an option to load. I’ve tried everything.

Here’s a paste of my server.cfg: http://pastebin.com/KKeiuKAt

What are the server specs. I’ve had a similar issue with my Linux box
