When ever I use air drop I get an invalid Apple certificate. I then go and delete my Apple user name in Preferences/Users and then reestablish the same user name and password. Air Drop then works but once I close finder it will not work again unless I go through the same procedure. How can I keep the certificate valid permeantly?

Mac Pro, Mac OS X (10.7.3)
