I don't use that program to backup my Outlook Express, so I can't tell you. Sorry.
I do (in essence) what Microsoft tells in http://support.microsoft.com/kb/270670. But some people (like you maybe) prefer to pay for a program with a GUI. Their choice.
I was trying to backup data from Outlook Express 6 using Genie Backup Manager Pro 8.
And it told me to select My Profile tab but I couldn't find any tabs concerning My Profile though.
As the Help shows like this:
How to: Backup Outlook Express
From the left navigation menu in the backup wizard select Where to Backup.
Select My Profile tab.
bla bla bla...
If anyone happened to be familiar with the software I'd like to hear from your solutions to my problem.
