Plugin not working

I bought this plugin last night and installed it on my server with a custom map on it. went to assign perms and it said they dont exist.  The plugin is failing to load on it. I then installed on my other server that has a procedural map and it loaded, but still cant assign any permissions. I have always manually added perms through the console, but after this issue, I installed permissions manager to try and get it resolved but it doesnt show up in that.

Hi, I'll check it out today and let you know 

Hi, check that the permissions are correct.
I just wiped a new server and everything is working fine here.
