Why can't I download anything from the Play Store?

[AC Question]

It displays: Error retrieving information from server. [RPC:S-7:AEC-0NSYM-6RZ5-ZSF3Q]

It used to work before I set my tablet to manufactured settings. That's another story.

Welcome to Android Central! Does this happen on both wi-fi and mobile data?

Try going to Settings>Apps>All, select Google Play Store, and Clear Cache/Clear Data, then Force Stop. Do the same for Download Manager. Now try again.

If that doesn't work, try going to Settings>Accounts-Google, select your Google account, and remove it completely from the phone. Then add it back again, and see if that helps.
