The link you provided is not working. Have you tested the app with latest version ? I have read the documentation of the app (3.1.9), in the given version the IOS support is for 6.0 and in the 3.2 documentation it supports 6.1.3 and 7. So to solve this problem you have to either use IOS 6 or app version 3.2.
