OK, my stock answer first
Can you please delete all cookies and temporary internet files on your computer, then close your browser and reopen it.
Then try logging in with your new password. If that doesn't work, then update here and I'll reset your password myself and test it on my machine.
I'll cc this message to your email.
*****EDITED TO ADD*****
Ok, I caught your password in your other post and tested it using IE and it logged me in no problems.(I've deleted the password out of the post now btw
)
Do as I said above, and then let me know if you can get in.
