Try this. See if BBM shows as an installed app in device options. If so, delete it. Then install BBM using desktop manager. Afterward, go back to app world and upgrade if it shows upgrade available.
Worst case you may need to re-install the OS. If you do, just selectively restore your personal data and not settings. So skip the automatic backup/restore and do a manual backup beforehand.
And don't double post.
