Thank you, Mark. I think I may have found out what it could be: I normally use a VPN (ExpressVPN) and perhaps there is something there that makes the VPN and the UC website somewhat incompatible. I never had this problem until a couple of weeks ago, though, so UC worked fine with the VPN on.
I could also try getting support from ExpressVPN, I have found their customer service to be just that, real customer service. Failing that, I will have to remember to de-activate the VPN before posting...
