Thank you! By resetting the password, it helps. I also realized that I need to use the cPanel in order to access my file, not through any FTP software.
Here is the message:
An FTP connection to "ftp.jessiemccann.exofire.net" could not be opened because the server rejected the password.
Contact the server administrator to verify that you have the correct hostname, username, password, and authentication method. Server responded:"Login incorrect"...
