I installed all the plugins listed to be required for this plugin to work and it wont load when I select it on the Event Manager under Admin.  It lists the Capture the Flag event under create but when I click it nothing happens.  I created kits called ctfkit and a zone called ctfzone.  

Have you checked your logs for errors?

Error while compiling: CaptureTheFlag.cs(121,50): error CS1061: Type `Signage' does not contain a definition for `textureID' and no extension method `textureID' of type `Signage' could be found. Are you missing an assembly reference?
