You seem to be not alone in this. Might be a bug on Google's side.
Wait and try again later.

just search on the google the play store app...

try this and see if it works go to settings- apps - all- Google Play Store- Clear data and force stop then try opening it again good luck.

To download from Play store you need to setup your google account first. Adding a samsung account will only allow us to download apps from samsung app store.
For play store you need Google account.
Goto->settings->Accounts&sync->Add account->choose google and complete the rest.
good luck

The touch player will only play music stored on the hard drive - not on the storage card or any other card you use - i don't know why! If there is music stored on the hard drive, have you updated the library?
