Membership 2 Pro/Coursepress Pro upgrade issues - pages not loading

Hello,

I have been having troubles with my site all day today. I keep getting the white screen of death when trying to access pages. Also, on CoursePress Pro pages just aren't loading in the admin area. And when students login, it doesn't redirect them to the course page -- just the white screen. Really could use some help troubleshooting this.
Thanks,
Darla
