What is the error you get when you try to load them ? The only way I know is by the error message you get

My first suggestion is to look at the Release of the Files you are trying to open, do you have a copy of the error ? I know alot of designers are running a later release, Like R21. Keep in mind Catia is NOT upward Compatible...So if the file was created with R21, you wont be able to open it with R16
