Yahoo Groups problem

[Blackjack Gabbiani]

I got this email earlier and was very confused

Dear Yahoo! Groups member,

You belong to one or more email groups provided by Yahoo! Groups
(groups.yahoo.com).

Recently, messages sent to you from Yahoo! Groups have been
returned to us as undeliverable. As a result, we have temporarily
turned off message delivery to this email address.

If you are reading this message, the delivery problem appears to
be fixed. To start receiving your groups messages by email again and
turn your account back on, please visit:

http://groups.yahoo.com/unbounce?adj=2720936,17715&p=1162119753

(You can also copy and paste this link into your browser, and hit the
'Return' key.)

Once you reactivate your Yahoo! Groups account by clicking the
link above, you will receive messages from your group(s) again.

Tip: You can read messages you might have missed while delivery was
turned off by visiting your groups here:

Thank you for using Yahoo! Groups!

But it said that it was fixed, so I tried sending a message to one of the groups I run and got this in return

We are unable to deliver the message from [email protected]
to [email protected].

Your email account has been bouncing mails. This means that emails
sent to your account over several days have been returned to us.
This is sometimes because mail boxes are filled up, or because of
configuration problems. To reset your Yahoo! Groups account, please go
to http://groups.yahoo.com/myprefs?edit=2

I went to the link it gave and there was nothing useful there. So how do I get this to give me my messages back?
