Hi Double T,
Is this for all Sample financial reports or only for one or some reports? I wonder if the ones with long file names are the ones you are having trouble with...
There should be no problems in opening the samples. If you do have problems for all of them, I would guess that a problem has occured during the creation of those particular file. Try sample data to see if those files are openable and if so, you can copy them to your live data directory; you have to change the file extensions from SAM to your data extension.
