After importing media on the time line, starting the editing process, I do a "save as" not only to name the file, but also so I can finish editing at a later date. When I try to re-open the file, I get an error message "Unsupported Format". According to the error message, the file is saved as a .vf extension and have to start over. This is a recent problem and according to the site, my software is up to date.
Is there any assistance you could give with this frustrating problem?
