To Sally, Yippee, I have managed to fix my file. I've tried this before and it didn't work, but this time it did and I now have a nice error-free file without having to type all the info out again. What I did was export the corrupted file as a Gedcom, set up a completely new database and then imported the Gedcom file. It told me there were a couple of errors which I fixed and then hey presto my database is error-free again. Hope this helps you too.
