Outlook 2010 does not open, error about file cannot be found

Hi, I was wondering if you guys could help me with a problem I have. I downloaded Office 2010 (only installed Outlook 2010) beta about 2 years ago and everything was going fine. Then today I purchased Office Pro 2010 and before installing I removed Outlook 2010 as it told me I must remove it first, then ran the install and everything seem fine until I tried to open Outlook 2010, it keeps coming up with a message that should be in the print screen or attachment, I have no idea what this file is and everytime I try to delete it, it re appears when I try to open Outlook again. I tired to do the set up again and select the repair option but that has not helped, other than that all other Office 2010 applications open fine, could this problem be down to the 2010 Outlook beta?
The attachment called error 1 is what appears when i try to open Outlook, empty file is what comes up when I clik OK, and error2 is what happens when i close everything.
Thanks guys for having a look, and I hope someone can help me with this problem.

yes thank i tired this and it has worked, many thanks
