Can't sign in to existing account & forgot password states my userid/email address isn't registered

Hello,

I'm trying to log in to my account on a new machine (laptop crashed) and after a number of attempts using my email addy and getting a "account/password incorrect" message I went through the "forgot password" flow.

The email I received states that my email address is not associated with a JIRA account. I tried a couple of other email addresses just to be sure. I continue to get email notifications from JIR on ongoing daily tasks and they're coming to the first email address.

Help! I can't work...
