Well, I didn't ever any spaces or extra lines in the config.php file, but I went back to the config-dist.php, and "redid" the settings in it for our organization. It didn't fix the files we had already uploaded, but anything that has been uploaded now (Word files, pictures, etc.) are working great.
Many thanks to Zbigniew, Matt, and Ray for coming to my assistance! The people on the Moodle forums are just great!!!!
