I've tried upgrading to the latest version of ACS, including running the migration SQL (we have SQL server). I'm able to fulfill existing books fine but newly packaged books aren't working correctly. The packaging tool reports a successful import but when I try to download the packaged book I receive:
Error getting license
I can see that the item column in resourceitem for this book is set to 0 when it should be 1. I worked this out from the packaging logs. I'm unsure where to go from here to work out why this value is being set to 0.
