Outlook 2003 not working at all

Have a new computer - a Packard Bell with Windows Vista Home Basic - I installed my Office Professional 2003. Everything working fine then Windows downloaded something or other. Since then Outlook 2003 will not work. I can open the page but I get various messages when i try to write an email or received. Registry or installation errors. Invalid parameters are the two most common. In the control panel mail I do not have any of the stuff I expected and what there is I cannot open.
Someone else here seemed to have the same problem. I tried the solution offered without any luck - it involved uninstalling Office, deleting registry keys etc - though most of the keys mentioned I did not have.
My Internet Explorer seems to be working fine so far. I am on BT broadband.
Please can someone help?

Did the PC come bundled with office 2007 trial? If so, was it completely removed before installing office 2003? They cannot co-exist, it causes major issues with outlook.

If it is brand new, I might suggest re imaging the machine and trying the office install again.

Yes, Thelteam3  it did come with 2007 but I got rid of that before installing 2003 - at least I think I managed to do so..
It is a brand new computer. I know how to install office again - I have the discs - but how do I image the machine?
AFraid I am almost computer illiterate!
Please try this first.
Office 2007 complete removal tool - http://www.mydigitallife.info/2009/01/03/microsoft-office-2007-complete-registry-removal-and-deletion-uninstaller/
Followed by Office 2003 removal tool - http://office.microsoft.com/en-us/ork2003/HA011401771033.aspx

Office 2007 does not always uninstall correctly. Which will cause this kind of issue.

The new PC will either have come with CD's for the reinstall, or when restarting, it will give a quick prompt for recovery. Something like F11.
Be aware, this will remove all data from the PC, and all installed applications.

Will try uninstalling 2007 fand 2003 as suggested, first and if that doesn't work will try recovery, and okay I'll save all my data on my memory stick.
As I am slow (my hands don't work that brilliantly) it will be some time before I get back to you as to how it works.
anyway here's hoping.
