OMG! I just found out that....what should I do?

I happened to be using the PSA Population Report and running a few of my cards and Blam! one comes up that it doesnt exist.

Background, rather rare t206 card in a PSA "authentic" graded holder with certification number and all that jazz... I ran the player with the set and back and it's not listed. Then I ran the certification number only and it's not in their records. I did use my Zbar scanner that does show the bar code matches the certification number but that's it.

I have the emails from the transaction and I think this person is current member here on the site. I have done other trades/purchases with this individual with no other problems. It was a two card transaction and the other card comes up fine. I do believe that it was an honest mistake on his part of buying the problem card and not that he pulled anything funny.

1) how should i approach him in the email or phone call?
2) could this number be old enough that it was never entered in PSAs data base?

thanks for any input, and I'd rather not post the member name or a scan of the card until this is settled.
