Upload Manager Help


I have a bit of a problem using Upload Manager. I am not able to login to the upload manager. I have a message saying "UNABLE TO CHANGE DIRECTORY..." or "USERNAME OR PASSWORD INVALID!"

I'm not sure whether I'm supposed to use the admin username & password I have created for phpALBUM or my login for my webserver.
Either that or FTP server is incorrect.

Any help would be much appreciated. I apologize if this is a repeated thread. Thank You
