7. Windows - "Invalid mph.license" message
If you get a message on the left bottom corner of the MP Host that the license is invalid it means that the mph.license file does not match the hardware of the computer you are using.
If you have copied the mph.license file from another computer delete both the mph.license and hardware.id files and run the MP Host in the DAW to create a new hardware.id file. To create a new hardware.id file, unload any instances of the MP Host plugin in your DAW and then load it. It will automatically create the hardware.id file.
The hardware.id file is a digital signature of your computer and your mp controller combined, so it is passed to the server to generate a license.
Then, log on your account (sent via email when you purchased the MP Controller) and upload the hardware.id file to generate a new mph.license.
The hardware.id and mph.license files should have these 2 exact names.
