What steps are you taking to load your project and media?
A project file (.prel) is added by going to File/Open.
Video, audio and photos are added to a project using Add Media.
Did you create your project in version 14 or in another version of the program? You can not open an older version project in a newer version Premiere Elements.
I wanted to continue the project, which I have elaborated (.prel). I started last week, I put the project and the program closed. After a week I opened the program and projects in progress were to continue. Unfortunately, the program began to report the errors described. The same error reports for all other projects which I tried to open it. All are .prel.
All projects were created in the 14th version of Premiere Elements Eight months this version you use regularly and never a problem occurred.
When opening the program loading the project window opens: Import Error. Error message: This file type is not supported or not installed the required codec.
After the project loads offline.
What are the properties of the media and where are they from?
