Lightroom 6.14 stopped working
Help please! Since a few days my legally purchased standalone Ligtroom have stopped working. I bought it as version 6.0 an registered in 2017. I upragraded it later to version 6.14. I haven't, any problems with it for five years. It is on the same laptop, OS Windows 7 Ulimate and installed Lightroom 6.14. Now when I try to run Ligtroom there is a message "Sign in Required". When I chose "Sign In Now", the next message is "Please connect to the Internet and retry". But I am surely on line. When I press "Customer Support" there is a message: "Your Adobe serial number has expired or is invalid. Your serial number has expired or was illegally distributed." It's surely not the case becuse there it was a lifetime purchase.There is a message on my Adobe account: You have no activated devices. I would be very gratefull if you be so kind and help me.
