It looks to me like Google Play Store has been hacked by someone phishing for passwords - the Tech in the local Verizon store agrees with me.

You might consider changing your Google account password - and change your password again immediately if you ever use your password on Play Store.

 

This a recent Jelly Bean thing? Maybe that's why Moto pulled the test update?

 

Reboot it a few times.

 

Lol...

You know my story with that one... right now I'd ALMOST say don't bother.



You could always try a factory reset.

 

When the update hit my phone, the Play store was unstable for a while after the initial reboot. I let the phone sit undisturbed for about a half hour and then it seemed to settle down. Since then it's worked without issue...

 

Or try a factory reset.
