Lyne, If you have anough space on your HD, you can do what I always do insteed of taking risks. I copy my whole Vue Folder to my HD e:, then update the copy. If it works, fine. If it doesn't, I go back to the old version. Don't forget that you need to have Vue 4.05 to be able to update. If you create a copy, there is another VERY important thing to know. Vue's updates ALWAYS install on the latest Vue used. Also, if you want to update the copy, open it first, do any thing in it, then close it, then update. :-)Guitta
