Saving as Movie error

[John]

After capturing all of the video and importing the clips
into the collections, I can save the Project (.MSWMM
file) with no problem. When I Save it as a Movie File
(.WMV) onto my computer, I get the following error:
'This project contains source files that are missing or
that have been modified after import. Your project cannot
be saved as a movie until the source files have be
located or deleted from the project.'
I have gotten this error when I have either left the
clips alone or when I have edited the clips by trimming
them according to the instructions in the help file. (I
need to trim to eliminate unwanted portions of the clip.)
All of the clips still reside in the collections.
Everytime I try to save it as a movie I get that error.
Also, I cannot copy the saved Project (with or without
the accompanied clips) to another location and view the
Project. When I open the copied Project all the clips are
red X'd out and only have the timeline.
Please Help............ What am I doing wrong?

If the original project doesn't have the red x's, try reading
