On-going problem that is stopping progress

The new user name is 'anne..........1' and this would appear to be the problem.
I can create Family Groups, various charts but, worst of all, I can't create a .ged file of any description!!
Warwick discovered that iFamily is using my original User set-up, storing everything there, however, when I go through to that original User all that appears when I open iFamily are those families that came with the original program, Royals, etc. Bit of a quandary here. I've added hundreds of people in the past year or two since upgrading my computer, I think I have the file stored at perhaps that old changeover level ... I don't want to go back and enter them all again!
Any thoughts
Thanks
Anne
