I have been using Outlook and Word for years now and have never encountered the problem I am having.. (Everything was working fine until yesterday) I have tried reinstalling Office 2003 Suite, and numerous other things but still keep getting same messages on screen.. Please can someone help..
When trying to reply to an email received, I get the following message on screen:


Microsoft Office is set to to be your email editor. However, Word is unavailable, not installed or is not the same version as Outlook. The Outlook email editor will be used instead. An OLE registration error occurred. The program is not currently installed. Run setup again for this program.
And if I try to send a new email, the following message appears:
Interface not registered.
Please help
