Photoshop Elements 15 suddenly asking for licence key I have a disc copy of PSE 15 which is installed on my Win10 machine and has been working quite happily until today. Now when I open the program, it demands the licence key/serial number. I have input this from the printed key on the CD sleeve, (making sure to enter the PSE one not the Premiere Elements 15 one also on the sleeve). There is a longish delay, then I am prompted to retry after deactuivating on one of my other devices (it is onloy on one other device, and both were working correctly simultaneously before today) or to try a different serial number. There is also a contact support link on the failure page, when this is clicked, it says the licence is either expired (it is a disc version so should not expire) or invalid (well it was valid last week when I used the program without issue). My colleague with her own licensed disc version in use on two machines is also experiencing the same thing today. Please note, I am not re-installing the program, or transferring
