Must be an age thing!
Just down loaded version 3.7.2 thanks for the link.
Seems to work ok with some sets of files, but still closes down with others. Will have to look at the files to see if there is any differance.

I had this problem when I did the very first update. Suddenly nothing would work. What I did was to scrap the lot, re-load from the disc and then downloaded the update again. It worked after that, but I left the original software from the disc intact. It may not have been that, but I'm happy to leave it there just in case it was.
