Decided to upgrade a second machine and install the new version of Mocha 2020. I read about the ability to deactivate/activate a single node-locked license between machines, so I tried this with terrible results. I got the deactivation screen on my primary machine, but was never able to activate it on the second machine. And now I cannot reactivate Mocha on my primary computer. Now both machines are telling me: “You have reached the maximum number of activations permitted with this key. You can purchase a an additional license or uninstall from another machine and try again 0x7f26da”. Your licensing server is clearly not working correctly. This is using the multi-host plugin in After Effects (I have the standalone and multi-host package) on a Mac running 10.13. I am using the activation key sent to me in an email at the time of purchase.
