Snapshot Pro fails without error message but screenshot of website.

Hi There,

I've tried to run Snapshot Pro a few times and every time I get the error message that something went wrong and a message was returned. Except there is no message, instead a stripped down version of the Upfront homepage shows, pushing the standard managed backup screen further down the page.

Some side notes.
This is a brand new multisite installation.
I have tried uninstalling all plugins I wasn't currently using.
I've tried using Dropbox and it runs fine.

I'd really appreciate some help.
