Zynga Slots Not Responding

My Zynga slots game won't load; it just goes back to the phone's main screen.  The only answer I've found involves Facebook.  I don't have a Facebook account.  Can you help me?  I've not been able to play or get bonus coins since Friday, October 26.  I keep checking the game and support areas, but I've found nothing.  I have the iPhone 4 app.  If you check, you'll see that I claim my bonus coins almost every time they maximize, so I'm missing lots off coins!  Thanks for your help.
