GOM Mix Max
I launched the GOM Mix Max to find the license deactivated.
Generally, the license may be deactivated in any of the following cases:
1. When you have logged out and switched to a Free version;
2. When your license has expired;
3. When the system or network information has changed from the time of license registration;
4. When the Internet connection is lost.
In case this issue keeps happening even though you haven't deactivated your license, please contact the Customer Service Center to find out its exact cause.
