itunes 12.2 won't launch on my iphone 5c
I recently upgraded my itunes to version 12.2.2.25
At first, I couldn't launch it on my MacBook pro, but I was able to remedy this problem. However, it still won't launch on my iphone 5c. When I hit the "music" app button, I just get a graphic with the apple logo next to the word "MUSIC" but nothing happens. I can't access or play any of my library on the phone. The library shows up fine on the computer, and the phone connects and syncs, but I can't use the app on the phone. Any suggestions are welcome.
Thanks!
iPhone 5c, iOS 8.4.1, itunes 12.2.2.25
