Hi, I just installed Premiere Elements 14 and licensed it. I worked on couple projects and everything was ok. I could export video to Youtube for previous projects. However, today, I tried to upload the video to Youtube. Not only did the video not upload, when I tried to reopen the project it says "the file is not compatible with the current version of Premiere Elements". It's the only version I've ever had. The incremental saved files that Elements makes during a project all do not work either. The program is installed on a 2014 Macbook Pro (OS X El Capitan). I would appreciate any suggestions.
