Loosing folders in EM Client 6

I recently tried to move my wife to a newer laptop.  To move EM client I copied the database from the old PC to the newer one.  While I was offline everything looked good and I had all of her folders.  When I went online most of the folders disappeared.  I went back offline and reinstalled the database but this time I created a backup.  Then I went online and again most of the folders disappeared.  I tried doing a restore of the backup and all the folders appeared then most disappeared again.  Can’t seem to get the folders to stay.  Anyone run into this or have any ideas as to the cause? its a real PITA

Thanks
