Falcos Prop Protection broken?

Last night on our Gmod server, FPP just decided to stop working. We didn’t touch any settings, we didn’t install any new addons, it just STOPPED.

I have already tried installing the latest SVN version, that didnt help. I seriously don’t know what to do. FPP literally shut down, like, it’s there, but I can’t load any groups to restrict tools, no props are ban or stay ban, its basically a build server now and its a mingefest, please help!
