I've been running V4.41 without problems for years. I was moving to a new Windows 7 machine and thought I should upgrade to the current version.
The upgrade went without errors, but when I was done, it told me it could not find my username.
I copied the old 4.41 program files back over the new install and all is working again.
Any clue on what I can do to get my old mail files found in the new version?
