Repeated notifications that product has expired when it has not
I am getting repeated notifications, on Winows 10, that my F-secure safe has expired when it has not. Another notification was that an upgrade was available which I successfully installed. Yet I still get constant expiry notifications. It does not happen on the four other devices I have the product on. I have even deleted the "Trigger" file to no avail. Before I get really cross and throw the PC out of the window, can anyone help with this?
Thanks & regards, Jim
