General principles...
Thunderbird files are stored two places. Your problem is probably with
the "Profile", which is where all the settings are stored. If for some
reason, you didn't have permissions to store things in the Profile
folder, that might cause changes to be lost.
C:\Documents and Settings\Username\Application Data\Thunderbird\Profiles\eight_digit_number.default
If you go to Tools:Error Console, you can see error messages. Now,
I updated to Thunderbird 6 as a test on a virtual machine, and can
see a fair number of warnings, none of which seems to be hurting
anything. You can look in there for actual errors.
In addition, you have Tools:Options:Advanced where there is located
a "Config Editor" button. Don't touch anything in there! First, see
if it will open. You can scroll down and look at the various settings.
Any changes in there, cannot be undone. The changes are immediate,
which is why I don't recommend touching stuff there. You'd need to
back up the profile, before starting Thunderbird, and then, you'd have
options for undoing any changes you made.
There is an install.log file in C:\Program Files\Mozilla Thunderbird
that you can look at. It shows what was done during the upgrade.
I would guess it's a file permissions problem, but have a look at the
available error information first. If the program will start, you
should be able to examine a few things.
