Promlem with ADCH + + and Freshstuff.

I've tried to put up a ADCH + + hub up, and have installed ADCH + +-PtokaX and Freshstuff. But I can not get freshstuff to run. I get this error (adchpp-ptokax.lua: 1834: Error loading the module "lfs" via "require") and do not know what that means?
I can not activate freshstuff.lua too

Can U help?
