User Name/Password in Advanced Guestbook

I know what my username and password is in the Advanced Guestbook but when I enter what it is it wont let me into the admin settings. Tells me that ive got an invalid username/password. I tried the default settings of test and 123 and that does not work. Can someone tell me how to change the password and user name or can you tell me which PHP file this information is stored in?

I get this problem too occasionally - I find that if I delete my cookies I can get in again.
