Cannot start Microsoft Outlook. Cannot open the Outlook window.

Hi,
I have been trying to create a new Outlook profile, on my Microsoft Outlook 2010. This is installed on my Windows Vista machine. I already have a profile created and that works fine. After my attempt to create a new profile on the same machine, I have been getting an error message with Outlook.
Can someone help me with the below given error message?
Microsoft Outlook
Cannot start Microsoft Outlook. Cannot open the Outlook window.
