Not able to install Hummingbird

Hi,

We are going through trail and checking how useful is this for us but we are not able to use full functionality.

We have protected our WordPress directory so that directory can not be created from plugin installer so we download and upload from FTP.

Have activated WPMU dashboard plugin and trying to download Hummingbird (*https://premium.wpmudev.org/download/1398828228_wp-hummingbird-1.4.0.zip) but its redirecting to my account page.

Not able to activate this, please suggest.

Thanks
