Try again ERROR on AppZone?

Wth is this?

Its always get this message when im click on the "play" button

Yes this is a very known issue, when i am on my emulator and i donot get any ads or try again errors i do the following to trouble shoot resolve this issue
1. I go to application manager and gamehag and clear all history every thing
2. i restart my emulator
3. I relogin and try again
4. If still not working after max 5 attempts i do more steps which i explain below
5. I reset the router and do all steps 1 to 4 all over again
6. Most of the times i keep on doing it over and over again patience is the key plus these methods explained above will mostly resolve your issue no need even to contact support or misty
Hope this helps

It's most likely caused by an unstable connection, though mostly just temporary. Try it again a few more times and if it's still giving the same error, try turning off and then on your Wi-Fi or data connection. Even if the ad actually plays without any more error messages, I'm not sure if there are any SG to be rewarded until now...

My guess is that the ad provider runs out of ad to serve to you
