Something already sitting where Documents/N1MM Logger+ should go — a file, or a link to somewhere that is not there — threw out of Directory.CreateDirectory before the program had a window, so the operator got a stack trace and nothing else. CreateFolders answers with what stopped it, and the program shows it in a window naming the path and stops there. NONEMM_HOME moves the whole lot somewhere else, for a station that keeps its files off the Documents folder.
