Update 5.0 not working

UPDATE: Sent an email to developers and got a reply quickly. They found the bugs, fixed them and now app is running better than ever. Excellent customer service. Ive moved my rating up to a 5.

I downloaded the latest version of what usually is an excellent product, but sadly having many problems. It keeps crashing and closing the app. You need to restore previous purchases, but it gets stuck on certain books and the loading progress icon just spins (then crashes). Hope version 5.0.1 is released quickly.
