When I try to initialize the project on AUP, I get back an error

Hi, I just created my project and everything looks good. I check the Validation Tab and there are no errors. I publish the project for AUP and so far everything is fine. When I try to initialize the project, I get back an error. Someone might give me an idea what might be happening.
