Richard watches the BBC through their iPlayer (and likely through a VPN) and now it suddenly takes forever to load on his laptop. It's OK on his desktop, though. Leo says the BBC has probably locked it down for international users. The BBC gets its money through a TV license fee that viewers pay for. So many people use a VPN to get around that.
Richard should contact his VPN company. It may just be an error in the VPN. He can also try testing it with a different network. If it loads normally, then that points to his network or computer. So the idea here is to eliminate each problem. He can also reset his browser. The problem sounds like it's unique to his laptop, though.
