Thanks for you input. She probably has a lot of data. Whilst I was on the phone to her she loaded iTones - it took quite a long time - she then said that it had files there (around 1300) that she hadn't downloaded and then proceeded to erase them. Of course I have no idea what she has done - hence the advice to uninstall and then reinstall the program and start from scratch. It seems that this would be wisest in the circumstances - given my experience when I downloaded and installed it this should work - providing of course that she hasn't picked up any nasties in her web travels. She has AVG and I have told her to do a scan.
I'm awaiting a reply to see if that was effective.
