This method is for ngage, i hope it works for 6600 too.
In the blue soleil main window
right click on your phone and refresh services
next step, right click on your phone and connect to Bluetooth serial port service
you should be able to connect now unless there is any serial port coflict in your computer. Pc suite worked for me for the first time, but now the Blue soleil itself is unable to make the connection to the Bluetooth serial port service, it is giving a connection failed error. so naturally pc suite wont work.
