Welcome to Android Central! Which device? 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.

Also, make sure you have a valid form of payment associated with your Google Play account.
