hi again ketchup, thanks again for your detailed instructions. we don't have a computer at home so have been trying today in the library but no joy unfortunately, I can't seem to right click at all.. going to try on a different computer at work on tues. wondering through doing some online searching if it might be because it is indeed corrupted. thinking maybe buying a new usb might be the way to go. fingers crossed I can get it going on tues.
