If you still have a dialog saying that you have Guru version blocked, restart the app, I mean restart it completely, swiping it out of the backstack. If it doesn't work, it's possible that your payment has not been processed. Google sometimes declines the transactions if for whatever reason it doesn't like the card. If that's the case, I suggest you to look through your purchase list, and see if this app has been purchased.
