unble to open attached emails, ACT 2011 and Outlook 2003

when attempting to open an email attached to a contact history I get the error "The command line argument is not valid. Verify the switch you are using"
Act 2011, Outlook 2003. Problem started after installing another program which "grabbed" the file association of .msg. I have corrected that back to Outlook,

There's a range of possibilities (including some different file associations) that can cause this. The MS KB has quite a few:

Many thanks for pointing me in the right direction, problem resolved. It was the file association, although I thought I had corrected it I reset it again and all now works OK.
