I've been trying to use this program. It seems to be an excellent utility - unfortunately I just can't get it to work. The very first stage in the process is the creation of a definition file. This I can do. The second stage is to call up the file just created and here's where it all goes wrong. The file has vanished from my system. It no longer exists - in fact it seems that in some strange way the file has got itself deleted.Has anyone had a similar problem - I am fairly tearing out my hair - and there is not a lot of that by now.Bud
