We've just upgraded our site from moodle 1.9.5 to 2.1.3+ and attempted to install the latest book module. When I go into the Site Administration/notifications page it tells me that I need to upgrade, as expected. After clicking the upgrade button it only migrates 29/32 books and just stops.
See screenshot snips below.
What's the best way to get around this problem?
Thanks,
Craig.
