Can’t Login Via Yahoo Web Host Blog Manager

I’m trying to login to post to my blog via Yahoo Web Host Blog Manager. Usually I’m able to go through this interface, click on “Add a Post” and go straight into my blog as Admin. Now I am routed to the Word Press Login page and everytime I log in, I get the “invalid password” message. So I click to retrieve my password, and after its emailed to me, the new password doesn’t work. I’m using v2.0 of Word Press and have had the same issue on both my Mac and PC. Have tried clearing cache/cookies, etc. Any help would be much appeciated! Thanks.
