fwiw, this is the response I received when I sent their support an email about not being able to connect to my Scottrade account (I use it for the dow jones news feed)
"We have reported the issues with the Scottrade feed to the developers. We are no longer billing for registration renewals, so if you already have a paid registration, it will be free of charge from here on. QT will prompt you to do a WebUpdate when a fix is released. You may consider getting a TD Ameritrade account. And TD Ameritrade has full integration with QT, including trading, free QT registration, streaming of up to 600 symbols at a time, 20 day backfill, etc."
