Cant open iCloud docs numbers or pages

For some reason I can't open any of my iCloud documents in Numbers or Pages. I just get errors like this

Number 3.1 (1769)

Pages 5.1 (1769)

OS X 10.9.1 (13B42)

I've signed in and out of iCloud. I've unchecked and rechecked the documents box and restarted my computer.
