Help needed: my Cubase LE AI Elements 10.5 gives error at start "could not connect to POS"

Hello ! I hadn’t use Cubase LE AI Elements 10.5 for some months ( during which microsoft pushed some windows updates) and now when I try to start cubase I get the error at start up “could not connect to POS. Click to abort”. The e-licenser program seems to be healthy and running.

My question is if anyone knows what the problem is. I do not want to attemp reinstall (unless it is the only solution) as it seems a bit complicated with the licenses activation/reactivation process.

I would be greateful for any tips. Thanks
