Uniop panel upload project problem

I have a uniop panel ER-04. I can communicate with the panel thru my designer v6.0 also get the panel resource. When i try to upload the project from the panel it's failed with communication error. I believe this panel have a password to protect the project from being upload or ir's being block for upload. Is there a way to break this password or bypass the password so I can upload the project from the uniop panel ?

Thanks
