The translate button here is not working for your post. The best that I can determine is that a Premiere Elements 13 project that you created cannot be opened.
Is that correct?
Are you getting an error message? Are you getting any "Where is the file.....?" messages when you try to open the project? Can you open a new project?
What is the computer operating system that your Premiere Elements 13 is running on?
Does the problem exist with and without the antivirus and firewall(s) disabled?
Did you move, delete, or rename files or folders that were imported into the project after you saved closed the project?
Please review and consider the Adobe document on troubleshooting damaged projects.
A lot more questions and answers but let us consider the above and then decide what next.
