I have an email that has a Publisher document attached to it. I believe the document was created in Publisher 2003 and i currently have Windows 2000. When attempting to open tht file i get the following error message "Publisher cannot open this file. this is not a publisher file. I tried changing the publisher from 2003 to 2000 and i am still getting the same error message is there anything i can do or why i maybe getting this message?
