I can not open an AE file anymore. It seems to be corrupted... How can I restore it or know why it doesn't open ? How can I do to open it and all the compositions inside ? I can send you the file... I don't think it is a problem of virusses !
Thank for your answer and support
You haven't given much information such as what sort of plugins are used in the file, what version of AE you're using, or any of your computer's specs.
Have you tried importing that project into another, working project?
The first thing to try is importing the project into a new AE project with the Caps Lock key pressed. If it won't import then you have a problem. This is why it's very important to either have Auto Save turned on or a workflow established to save versions of your projects. I never loose more than 10 minutes work.
