Fail to open rhino 6 (expiration)

M5%24%5B%24RR1_T%5DZSZP13RWQMI4 I just purchased a license today but I still got the expiration notice. I have tried to reinstall but it did not work. Is there anything i can do?

Hello - that does not appear to be a Rhino generated message. Are you running any plug-ins as well as Rhino?
