Password suddenly not working?

[Jack I]

This is a very odd thing that's happening to me. Up until now I've been able to log in perfecty fine, but just now when I tried to log in it said "username or password bad". "Well, OK thats fine, I must've entered it wrong", so I go back and make sure I type in the correct thing this time. Still wrong.

I would say that it's me, but when I went to go get the information to retrieve my password, I used the exact same password and it let me into my information just fine. Anyone else experience this problem?
