If you've made a Deposit via Paypal but do not see it in your Account, do the following:
1) Log out and log back in
2) If balance is still not showing, but you see the deposit in your Account Summary page: Contact Support by using the Red Support tab on the right of this page. Notify them of the Email address you are registered to TapIt with, the amount you deposited and when you made the transaction.
There is a known bug with Paypal accepting the first payment from international advertisers. We are trying to resolve.
