Downgrade your Premiere project files.
Many Premiere users suffer from compatibility between versions. A Premiere project (.prproj) created with a higher version cannot be opened with a lower version of Premiere. Converting a Premiere project (.prproj) in ProjectVerDown will make the project open in any version of Premiere. A simple application with no additional settings or features.

How to use
-Launch ProjectVerDown.
-Check the required options.
-Select the Premiere project (.prproj) whose version you want to downgrade. (The original file is unchanged.)
-The converted project is saved on your desktop.
