Smush Pro Update Problem

So, I was running updates from my hub this morning, and Smush Pro didn't update, so I logged into the Wordpress dashboard, and clicked to run the update from there. That's when I noticed that smush pro had been deactived in my WPMUpro plugin. That's kinda weird, so I clicked "Activate". Then my site went down...
I can't access the front end or the back end of it. What's odd is that the uptime monitor in the hub shows that it it still up. It's not. THe next backup is scheduled to run later today. I I revert to lasy week's backup I'll lose ALOT of work.

Any help would be appreciated.
