I'm new to MapTool and I'm having trouble using the pathfinder framework.
I've downloaded the .cmpgn file and I've been able to load it, but when I create tokens they only have the basic property set.
Welcome to RPTools!
You need to double-click the token and assign the "Pathfinder" property type on the Config tab of the token editor dialog.
MapTool defaults to using the "Basic" property type and since the framework doesn't put all of the properties there but into the "Pathfinder" set, all you need to do is change it. Once you have you can save the token and the saved token will have the property type in it so when you use that token later no change will be needed.
