Thanks a lot for your tips. I already tried to opent it on one other computer. I will continue trying.

I can see the files, but when I tried to save them, the programme was closed down. And they no longer exist on the old disk, because I didn't want to risk my baby brother opening my pornographical writings and getting scarred for life. He's read Harry Potter, he would regocnise the names, and so I chose to delete these files before he took the disk. That's why I am reluctant to have people sort it out for me; it is a somewhat delicate matter...
