Getting problem in Sendig Email from new version

Hi,

I have just downloaded a trial version of office 2007, with office outlook
express. I had to uninstall my old 2003 version and have lost all the data
contacts etc. I am running an old version of outlook express version 6
I think so i could receive E-mails temporarily.

i now however can send e mails from the old version to the new but the new wont allow me to send any e mails at all . As all the buttons for send and forward or reply etc are disable.

Any one can help please?
