Not long after posting, I discovered that I couldn't play youtube vids either. I did a system restore, which fixed it and the password problem, so it all seems to be working again, though I don't know if I did something wrong in the transfer between computers.
Edited to add that the system restore has deleted a load of stuff I carried over. To be honest I think I will copy the stuff on the old one to a USB drive and put it on the new one rather than use the bridging cable. It said in the blurb that I would be able to choose what I copied over, but I can't recall getting a prompt for that, and ended up with load of stuff I didn't want to keep onto the new computer.
