I actually purchased " a better camera" for the following reasons

quicker image processing (4x)
ability to set as default camera app
more settings

also I saw it as an oppurtunithy to reward and encourage a developer who has written and published a good app for our platform, and also provides decent support as well as a decent free version.

Getting back to the matter in hand. I would google for the website and send support an email directly as you have purchased the app. they are extemely responsive and helpful. although you might not get an answer until they get back to work.
