Fotographer, maybe you didn't read all the threads above. 123 has a glitch and they sent payment to the email addresses listed under "correspondence", yours must also differ from the email account recorded under "Paypal" in your account info. In my case, I have no Paypal connected to my correspondence e-mail so my payment will bounce back to them even though I received a "you've got funds" message at that e-mail address. You likely do have a paypal account hooked up to your "correspondence" email address for your other agencies - so you likely received the payment into the wrong account also.
They reported here that they caught the error before ALL payments went out so they halted the rest of the payments (Lisa's was late but now she has it). My payment has still not arrived to the proper account, but they said they are working on it.
