account key mailing

I recently rebuilt my PC and am trying to re attach to my Einstien@Home account under the e-mail 'nerdcentral@hotmail.com' but don't have my account key. I have tried at least 10 times now to have it automatically e-mailed to me from the site but nothing every arrives. I have confirmed it is not being blocked by my ISP and have successfully received account keys from the Seti@Home and climate prediction BOINC sites using the same facility.

Can you help have my account key e-mailed to me please.
