Error trying to download apps

[AC Question]

I cannot download anything from the Google play store. It keeps giving me an error. Error retrieving information from server. [RPC:S-7:AEC-0] What do I need to do to be able to download things from play store? Thanks

Welcome to Android Central! Go to Settings>Apps>All, select Google Play Store, and Clear Cache/Clear Data, then Force Stop. Do the same for Download Manager. Now see if it works. If it doesn't, then try removing your Google account from the phone, then adding it back, in ​Settings>Accounts.
