Ah... That makes things a little more difficult...
I'll have a quick fiddle about in the VA system to see if there is anything I can do there for you...
EDIT: Nope. Don't even get to see the email address you have registered with. Given the unstable nature of the IVAO network at the moment, I'd suggest leaving it an hour or so and trying again with the password reminder service.
FURTHER EDIT: Not strictly true...
Member ID: 182781
Details have been mailed to the address on file for this account.

When I re-got my passwords yesterday, the mail headers were:
From: "IVAO" <reminder@ivao.aero>
To: <murray AT not DOT telling>
Subject: IVAO Reminder
Date: Fri, 25 Nov 2005 18:47:17 -0000
If you still don't find that email, get in touch with the IVAO membership department directly (although I suspect they're going to be busy...)
