PB 1-525 Leatherworking + Skinning problem

I have Skinning package to HBProfile section, and I put the XML in the bots/professionbuddy/profiles folder. Every time I try to run the profile it gives the following error msg:

Err: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentNullException: Value cannot be null.
