Hate to bug you again Nickeny, but the demon trainer module is also checking for the notes module and spitting out an error. Sorry, I don't have the exact error on hand atm, but I imagine you probably know what's going on.
I never understood why anyone would need a note to tell them where a trainer is. I find the trainer once, by asking a guard or whatever, and I know where he is from then on. I only visit a trainer every so often, never really needed a note for that.
