“License Invalid” with Musiland 2.3.0.0 Driver
If you are getting a “License Invalid” message with this driver version (or newer), you may need to request an authorization key from Musiland.
I was getting the “License Invalid” message when installing this driver on my Musiland O3 US. Requested and received the authorization key. I’ve documented the procedure in the “Musiland” tab

Hi,
I’m using the new Musiland 2.3.0.0 Driver with a 02 US without any problem. I’ve had the 02US little over year and half so I don’t get why a newer 03 US would have License Invalid and didn’t.
Yeah, according to the responses in the Musiland forum, the problem happens to some devices and not others. Not sure what the real story is, but it was very easy to get a new authorization. In addition, there was really no need to get the newest driver except to “have the newest and latest” 🙂
