Glad you're still able to save okay, Genny. But that's a Microsoft message, not a Vue message, so I'm not sure what to suggest for you. Are you using XP? You may want to do the usual Windows stuff, like check your drives for errors, de-frag them. Then check if you're still getting this error message. I don't know if sending the report to Microsoft would do any good or not. It may be necessary to reinstall Vue.
