We are getting "License Expiration Error: license expired on 1-Jan-16 19:32:55" message in our PI data archive messages. How we can update the license?
The following two articles could help you:
KB00290 - What happens when a demo, temporary, Try and Buy, DevClub, or vCampus license file expires?
KB00303 - My License Activation (MLA) - How to get a PI Server license activation file
I have marked Luis answer as correct as I assume this answers your question. As you get used to PI Square you can do that as well
Have a nice day and see you soon on PI Square!
