Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
Im assuming you have a full paid version of pinnacle,and you arent using a trial or pirated version.
With that being said, this error usually represents and error with your licensing file. If you would like, I can connect to your computer from here and resolve the issue personally, on screen. This can be accomplished via a secure remote connection.
If you would like to try a secure remote session, please accept the offer I have sent you and we will continue.
If you would prefer written support, please respond and let me know what version of windows you have and we will get started.
