If you don't have much memory you need to make sure that you have a lot of available space on your hard drive so that there is enough virtual memory available for Vue to run correctly. I'm assuming you're using Windows. Make sure your virtual memory is set to adjust size automatically. Once you've made space it's always a good thing to run scandisk and defrag. Also you might want to run a diagnostic on your RAM to make sure you don't have any bad memory cells there. Please note: The defrag routine built into Windows isn't very good. There are a number of 3rd party programs that do a much better job.
