Thanks for that. I’ll work my way through your suggestions. I should have mentioned that I’m a reasonably savvy PC user, who’s used this VPN (Premium version) for many years, so I’ve tried all the obvious fixes in your list, but I’m stumped by this latest problem. As for the lack of response from the lab, I was in a phone chat with Support, which ended with the techie’s saying he’d refer the problem to one of their experts and get back to me. I’m still waiting, and Support has now logged my query as “Resolved”. Not impressed. I’ll let you know if anything solves the problem. Thanks again.
