Google play always asking account

view story

http://androidforums.com – Dear all, I'm using smartphone lenovo A366t and I have setup an email account on the device. The email client seems working just fine. Now the problem is: everytime I'm opening google play, It always display this message: "You must add an account to the device to continue. Do you want to add one now?" Everytime I click the Yes button, the google play app just shutdown/quit itself. Any help will be greatly appreciated. Thank you Nairfa (General)
