The urlresolver was hosted on the Collosus repo, which was taken down by the developers after they got a cease and desist letter. The tvaddons.co repo should have the latest copy (as probably others). Hopefully someone will step up and take over development, otherwise a lot of add-ons that depended on it will degrade over time. There was nothing hosted on that add-on, but since the media companies like using broad strokes against "pirates", the seat got too hot for that developer and he bailed.
