@DrJeff You shouldn’t need to change permissions of any of the addon files. This should all be done for you when it is installed. Perhaps your playlist file (in your squeezebox playlist directory) is read-only or something? The only other thing I can think of is maybe one of your params has a space or a weird character in it that the addon/script isn’t handling correctly. Hopefully the new version fixes any issues you are seeing. EDIT: If not, please give some more details about your setup. (Version of LMS Server, machine it is running on, type of squeezebox players, etc.)
