Changed hosting and now receive Error: Invalid username or password

I moved my web site that has Gallery v1 installed on it and now I'm unable to log on. It says my username and password are incorrect, but they are the same that I have used for a long time. All of my photos showed up with the move, but not being able to log on is a bit limiting.... Thanks in advance for your help! - Kristin
