Can’t log into my hotmail account on my nokia 900.Error message says incorrect e mail or password.

I can't log into my hotmail account on my nokia 900 phone.It keeps saying the e mail address or password are incorrect.I've changed the password numerous times so the password is correct.I can log into the account on my computer.I hadn't logged into the account in awhile and was told that that could be the problem.I was also told that there was a lock on my account.I filled out the profile information on the account.It was blank.I'd like to know when will the lock be removed from my account.It's keeping me from using my skydrive and other apps.Any help would be greatly appreciated.
