My license is not accepted
- Expired trial: buy a subscription and assign a license to this Mac.
- Wrong Mac: a license file only works on the Mac it was made for. Compare the serial number in the License window with the one in My licenses.
- License freed: if someone revoked the license, assign it again or use another free license.
- Offline for more than 72 hours: connect to the internet and start M-Client again.
- Moved recently: a license can move once every 30 days; the License window shows when it can move again.
