In this case, the application shows that it is activated on the customer’s computer however when the customer tries to save the files, the application says that the customer needs to activate the application in order to recover the files.
First, we ask the customer to restart the computer system and check if the problem still persists. If the problem persists then go to C:\ ProgramData folder, there would be a folder named as "KeyBase", if it exists, we need to permanently delete it. After this remove the application, install the application again and a new key needs to be provided to activate the application.
