Hello and welcome to android Forums. My name is SolApathy & I will be assisting you with your question submitted through the guest “ask a question” service! We would like to welcome you to our forums; we look forward to assisting you today!
Based on your question I will assume you are not having a “no connection” issue since you are stating that it’s just the play store. I can give you a few suggestions:
First make sure you are on Wifi. Remove your WiFi network, and power cycle the router, now re-add your network to the phone and try it.
If that does not work move on to the next step:
Settings>Apps>Manage Apps> and find the Play Store app then clear data/cache on the app. See if that clears things up.
Finally, if you still have an issue:
Are you getting an error message? Back up everything using sync. Then go to menu,settings,accounts,Google, hit your gmail.com account at the top, then remove account. After this you will need to sign back into your gmail account and re-sync.
I hope this answer has assisted you with your issue!
