Smush Pro not activating on site, only regular Smush is working.

I have a subscription for WPMU and I have Smush Pro and humming bird installed and working on a few of my sites. I have tried logging out and logging in, installing and uninstalling. I am trying to use it for my site and it only gives me the free smush version. Again Smush PRO is working fine on my other sites. Just not this one
