Get blank page after activating Buddypress Magazine theme.

Hi,

I have the latest version of buddypress and have uploaded the magazine folder theme to wp-content/plugins/buddypress/bp-themes ... When I activate the theme the site is just a total blank page.
I can only get the site back up by deleting the theme via FTP, where it turns on the default theme.

I've also tried installing the theme on wp-content/themes directory but the same thing happens.

Also, I've read that I should have 2 themes .. parent and child? Magazine theme only comes with 1 as far as I can see here.

Any ideas why please?

Thanks
