1. Download the latest 'GMG Application Service' from:
   https://gmgcolor.com/support/software-download
2. Close all GMG applications:

3. Double-click to install the 'GMG Application Service'
4. Open the license window and wait a few minutes
5. Is the serial number recognized and are the licenses displayed now?
6. If not: Please create a device file: Open the settings > Create device file...
   
7. Send the file to: license@gmgcolor.com
8. You will receive a license file to activate the system again.
9. Import the license file

Situation 2: No hardware change

If you didn’t change major hardware components or integral parts of the environment of your machine:

1. Restart your machine.
2. If the serial number still cannot be recognized after a restart, click the “Refresh” icon and wait at least 10 minutes. The self-repair function sends requests to our server and the response might take a few minutes. Do not click any other functions while waiting for the server response.
3. If the serial number is not automatically restored after a few minutes, please install the latest AppService. See above.
