App crashing way too much!

Using IOS 4.3.4 on iPhone 3GS
Downloaded this app about 5 days ago. I have tried to listen to LBC everyday since using this app and it may work for about 5 minutes, then just closes unexpectedly. Sometimes opening the app does nothing except open the app, no sound, nothing. Closing it and re-opening sometimes works, but not always. I got it to work for 30 minutes continuously -- one time. I usually have to re-launch the app about 20 times during a 30-40 mins time frame if trying to listen. I am giving up until a fix is found.
