Not sure. Let's presume that your Money 2005 was a US version that you have had installed for a few years. Let's presume that you have not attempted to reinstall Money 2005. Or let's presume that your Money 2005 is not a US version, and it was installed
from an install file linked-to in the second posting in this forum.
Your Money 2005 Money file and backups have different names from your Sunset files.
So if your Money 2005 install is working, I wonder if you somehow tried to open your Sunset file by mistake. And Money 2006 remembered that wrong file. When it is asking for a password, then click on File at the top and choose your Money 2005 Money
file instead. If that does not solve it, choose your latest Money 2005 backup file. If that does not solve it do you have earlier backup files? Do you have any *.m14 files and what are their dates?
If you want more ideas, tell us more along the lines of the presumptions etc.
