Hi, Carmen: I am not an IT person, but I think maybe I can help. If you can't find it in Catalyst, go to "Start." Click on Search and scroll down until you see "Click here to use search companion." Then click on "All files and folder." Now put in the exact file name that you lost. Windows is searching your C Drive. Your file should be listed, and if it is, double click on it and it will open in Catalyst. At least it worked for me before...Hope that helps. I think between all the helpful ladies who responded, we'll get you back up and running...
