Daily Bonus Stopped on CK Zombies

Docentjoel

So I have been happily playing CK Zombies for some time and enjoying the daily bonus cash and gold each week. In the past few days the bonus has stopped and it indicates I need to be online to receive. Well, I was online when it happened the first time. This past time, today, I ensured I could get to the Internet and ensured that I was logged onto Game Center. Got the same message and no daily credit.

Thoughts out there?

Thx.
