You'll need to check that not only the project settings, but also the instrument settings are the same.
Check the 'Instrument' menu option from the main project panel and see if there are any .fp files listed. To make the project portable include these in the project itself.
Not sure if this is your problem, but it was mine when I tried to compile someone elses project last week....
