9-16-10,  Possible return unit problem.. I am trying to track this returned unit SN MBO30114,  that is having an update problem.  I sent it to your PO Box 1924; Allen TX,  75013, on 9-11-10, via Priority Mail.   Per USPS tracking, it is at this PO Box since 9-13-'10 waiting for PU, pls confirm that you have received it.   I have sent you some an email's with the post office tracking notice today.  The problem may be: per the notice it is at a different zip @75002,  Allen TX, waiting for your pu.   As I understand it, a certain PO Box is always related to a certain zip code, if a wrong zip code, possible wrong po box.   I got your return address from the shipping document. dp
