Pack and Go, save to zip option suddenly not working

Anyone have a clue why the "save to zip" option of pack &go would suddenly stop working? I use it all the time for backuppurposes, and to send customers the latest set of files. Suddenlythis afternoon, no zip file is created. The "save to folder" optionstill works fine. I tried cleaning the registry (so it's likeSolidWorks is brand new out of the box), and it still doesn'twork.SolidworksGeneral
