Blank admin area after updating ultimate branding plugin

I just ran the latest update for the ultimate branding plugin and after updating I now have a blank admin area...

I read that someone else had this same issue but there's was resolved with a plugin update, not sure which version they updated too - https://premium.wpmudev.org/forums/topic/my-site-backend-is-blank-after-updating-ultimate-branding-plugin

A few questions for you...

1. If I delete the plugin to get access will all the information I have set for the plugin still be there when I reinstall/activate it?

2. Can I get a previous version from somewhere in the meantime?

3. Whats the long term fix for this?
