Untrusted Activation Key

I cannot access lumerical because it says my activation key is untrusted. I tried restarting the license manager but that did not work. I am not sure what to do next.

Thanks,
Zack

Was there any changes or upgrades done to the machine where the license is activated? Please refer to this article on our KB on protecting your license:
