I was using my TF 300 last night and think I accidentally deleted the app for the Play Store. Now I get a message that app is not running. My main symptom is when I click on the 3 dots in the upper right corner, I see all my apps - but when I click on SHOP I get a quick message about do I accept or decline but the window quickly closes and I am back to the main screen. So I can open the SHOP app and download anything. I am backing up my apps and going to do a factory reset - will this fix the problem. Hope so! Thanks Dave - Oh is the best way to do a factory reset to go under settings and select Reset Tablet?
