FM Radio App keep crashing.

[WPCentral Question]

I have recently updated my Lumia 520 to windows phone 8.1, and i see that FM Radio has been separated from music+videos that's fine but when i try to launch FM radio it displays a black screen saying loading... and after few seconds it crashes. however when i reboot my phone, it works fine, and after using my phone for some time, when i again open FM radio, it again crashes and continue this behavior until i again reboot.
Please help me in this issue.

Boy, that's a tough one! Tell me, are you enrolled on the developer preview program? And what's your phone region? Are you on Cyan or Black?
