Pandora login invalid

[stv]

I have a squeezebox Classic 3. I bought a new laptop, a Dell Precision M4600 w/ Windows 7 64 bit, about 3 months ago, installed the Logitech media server app and set everything up so it worked fine. Two weeks ago I opened the app and got the message "invalid pandora login information". I called tech support and they could not come up with a fix. I uninstalled the Pandora app, removed the checkmark in Web Control, reinstalled SBS, rebooted computer, checked box in web control, and reinstalled Pandora. I went to the Pandora website and re-entered the account name and password. I still get the message "invalid Pandora login information". Any help is appreciated!
