Thanks.
Sony's European website doesn't offer the downloads. The US website does, but the download (despite claiming to be windows 7) fails with a message that the download is vista. The PC has a partition backup and didn't come with a CD. There doesn't appear to be any simple way of re-installing the camera driver without returning the computer to factory set up.
I was hoping somebody had experienced this before, and had found a strightforward fix that I hadn't been able to find by googling.
Ah well...Sony. Phone. Credit card!
