Sorry, about this, I am frustrated for you.
I have an off topic question for you, what time is it, for you?
It is about 12:35 am for me in the US.
Forgive me, at the moment, I am not up to reading through this entire thread again. If you could answer some questions that I may have already asked.
Did you install an anti-virus program after you installed Outlook 2007?
What anti-virus program are you using?
When you removed the other profile, did you set Outlook to "Always use this profile", for the remaining profile, when Outlook is started?
