My Book World Edition - Wrong Password

Hello,
I have My Book World Edition installed on my wireless internet. It was originally installed through my desktop. I purchased a Dell Laptop Vista 64 bit. I started to install the 'My Book' on my new laptop. I typed the login name and mistyped the password [without realizing it] and hit enter. I hit enter just as I saw a windows dialog box pop up asking if I wanted this computer to remember password. I couldn't react soon enough to stop it. Of course it comes back that it is the wrong password. MY PROBLEM now is when I type the correct log in and password, it keeps reentering the wrong password. I figured out how to click on Tools - internet and turn that option off and to click the general tab and delete the history of forms and password. However, it stills enters the wrong password. I can't uninstall because it didn't get far enough along to pop up in the uninstall. But I deleted the folder and then again deleted form and password history, rebooted, then reinstall and it still keeps overwriting the correct password and puts the mistyped password. I've been on the computer for 4 hours now trying to figure this out. HELP!
