I got above message without any reason

if it’s a hard reject, move on to something new. submitting the same project multiple times will suspend your upload rights.

I have changed the entire structure before re submission. But still they are not providing any reason behind rejection of my project. Always i got same rejection email. Please help me to let me know what is wrong in my project.
