question about application for PhD

Dear Campus Center team,

Hi, I'm Jingyi Cui. I've got the admission letter from the department of physics. But I didn't upload the file when I applied for the PhD in the STiNE website. Now, I can't make a new application. How can I solve this problem? Is it possible to reset my application?
My email address is jingyi.cui@desy.de. Thank you for your help!

Best regards,
Jingyi Cui
