Hi,
We just checked: The download works.
There is probably something wrong with your account. In order to be able to help you better, please write to campus (please no spam) @ (please no spam) allplan.com with the email address with which you are registered on campus.allplan.com and describe your problem as precisely as possible.

Kind regards

this is much easier:

Your Student licence was approved on the 3. of june. just logout and relogin to get the new approved status.

greetings
