Thanks for your help. I have just had a session and have 'sorted' it, I think. It appears after I cleared list and did another operation it always asked project ? has changed do you want to save it. I was hitting yes and overwriteing my original with an empty list if you see what I mean. It is a little confusing for us beginners but my wife has a great show which we fortunatly saved to disc first before we lost our files and had to do it all over again as we had before.
