App crashing on iPhone 4 with iOS 5.1.1

There are five icons along the bottom of the screen. "Gauges" works and I can also access the "More" page. However, clicking on Graphs, Sensors, or DTC will crash the app every time. Im connecting successfully using WiFi. I want my money back! NOTE: I upgraded my phone to iOS 6.1.3 last night and the app is now working. Not sure why the info says it is optimized for iOS5.
