XiiaLive Pro App is an older version in the Amazon App Store. Crashes in Android 4.3.

I am running Android 4.3 on a Nexus 4. I have purchased XiiaLive Pro from the Amazon App Store. The latest version they have is v3.0.1.2. This causes XiiaLive Pro to show a pop-up and says XiiaLive has crashed, but it stays running. I contacted Amazon, and they said you have to update the app and get it approved by them. I know the latest version is v3.0.2.5, but they do not have it on their app store. So now, I can't use XiiaLive Pro, which I've paid for.
