I'm sorry to hear that your app is crashing after the IOS 6 update.
Unfortunately, we aren't able to update those apps any longer, as the software that we used (the Stanza ebook reader) has been discontinued. We do have a couple of ways around this problem, though. You can extract the ePub ebook file from the app and open it in iBooks by following these instructions -
Alternatively, we can give you access to the ebook on oreilly.com.
To do that, just create an account on oreilly.com.
Then, send a screenshot of the apps that you've purchased to firstname.lastname@example.org. Be sure to include the email address you used to create your oreilly.com account. We will send you a link to the ebook when we've added it to your account.
I hope that helps,
