Pages update Dec 2012. MBP not syncing with iCloud.

I desperately need some MBP/Pages help. Since two days ago coincidentally when I update Pages for MBP and iPad, if I update a Pages document on the MBP it continually says 'Waiting'. So I login to icloud.com and see that the docs are not changing but the iPad 1 is fine - edit a doc and it changes at icloud.com within seconds. Yes, Documents & Data are checked in iCloud within System Prefs. There is one slight concern even though Mail is syncing, I have noticed that in Sys Prefs> iCloud, Mail is always unchecked. If I check it it stays checked until I close Sys Prefs. Got any ideas? It's driving my nuts and has almost consumed 5 hours of my life that I will never get back.
