B.Net Game Loading Problem

Earlier today I played Hearthstone. The game crashed on me. I didn’t catch the error and assumed it was a typical crash. Come to my attention when I went to restart the game, the Play button on Battle Net is grayed out. It reads:
Playing Now" Game is running.

Well that’s interesting because it isn’t. I’ve closed down Battle Net in hopes that it would reset the game. It didn’t. Even tried to see if I could do a repair - that option isn’t even available. How do I fix this?
