Upgrade Information If you're upgrading from version 1.4.x, your lists will work fine with 1.5. 1. Backup your Files Folder containing all of your lists. 2. Drag the ListMeister 1.5 application into your ListMeister folder and run the new version instead of the old one. That should do it. Please make sure that you backup your lists just in case something goes wrong. Better safe than ticked off.
