Yahoo e-mail issues

[Travis Retriever]

OK, one of my yahoo accounts puts me in an infinite loop of verifying my password whenever I try to log in.  At first this was just me mail, and I was able to find a back door via this:  http://mlogin.yahoo.com/w/login/user?_done=widget%3Aygo-mail%2Fhome.bp&.intl=us&.lang=en&_httpHost=us.m.yahoo.com
But now, it won't even let me get into my mail via that.
Nor can I get into anything in it.

The kicker? It's just with this one account, that I use for lots of important stuff (school, for example).

Now, I've tried Google for this, and Yahoo Help.  I've tried to keep entering in my password, I've tried changing my password (several times), I've tried waiting it out for hours (this has happened before).  So far, no go.
I've even looked in horror at Yahoo Answers and seen people who've been left to dry by the Yahoo Support people.  That is, the people having this issue were told they'd be contacted after 72, but were left to dry.

Has anyone else had this happen to them, or have had it happen to them?
If so, what did you do?

Tried it.

And oddly enough, it seems to be working now. O_o

Thanks anyways, for the suggestion, though.
