Stereo Tool

How does it work? What if I'll change the computer on which Stereotool is installed? Will it work on a broadcast computer without an access to the Internet?

All of this is no problem. You can use it on a different computer later, and if the pc is not connected to the internet it will also work. (Actually, I think for safety it's probably best to not have an internet connection on a broadcast pc).

How to register two serials? to get one working stereotool?
I've got here a serial for declipper (fm-mode, unregistered option in use)
and antoher serial is only de fm-mode ( so declipper is unregistered option)

If you want me to combine them into one new license, just send me an email.
