IReal Pro doesn't play back

My iReal Pro's play back function in my iPad suddenly not working. All other functions of the iReal Pro work properly. I have been trying to find out what could go wrong but without success....:(

Have you turned the device COMPLETLY OFF and then back on...then re-started the app?

If that's unsuccessful, the next step is to backup your songs and playlists Settings>Backup, and then delete the app (in the iPad's settings). Then using the SAME account that originally purchased the app (so you won't be charged again) re-install the app from the App Store.

Please post your results.
Sorry for the hassle,

Thank you Bob.
I turned the device completely off and it already worked. Thank you, it makes my day.
I will keep it mind your second option for future needs.

Thanks for letting us know.
These new-fangled gizmos sure behave in mysterious ways...
