can not download dashboard plugin

Ive found the download page at:
https://premium.wpmudev.org/project/wpmu-dev-dashboard/

but if I click the link the download link turns into a wp-login.php file.
I have tried clicking it in a couple of browsers and right clicking it and also entering the download link into an ftp client but all just switch to downloading a wp-login.php file.

Can you help please
