I am using MS Project 2007. My classmate send me a file which my Project says was created in newer version of Project and I need to convert it. When click to Download Microsoft Office Project 2003 Service Pack 3. I have MS Project 2007 and I don't want to download 2003 pack. What should I do ?

Hi Anderson
What you need to do is ask your classmate to save his plan in MS Project 2003 version and then you will be able to open it.
For some reason saving a MSP2010 file to 2007 does not work. I have had the same issue.
Hope this helps.
