It is also possible that your e-mail is bouncing them. If you tried to do as the others suggested, and it does not work, try changing the e-mail address in account options. See if that works.
If you need help, go to the Account tab, then on the left side of the page, you can scroll down to e-mail address and update your address.
Just remember that if you change your e-mail address, that you will have to sign into Fusion using the new e-mail address.
