Hey Judy! Have you checked the original listing/page of the scripts you're using to see if there is an updated version to download?
Otherwise, most of your issues might be because of Neopets switch to https. A quick fix you can do your self is adding an inclusion line for https URLs as well, for example:
Code:// @match http://www.neopets.com/* // @match https://www.neopets.com/*
