Joan, you must have figured out entering your DNA test information because it shows on your profile and on the ancestors that you have entered. For the GedCom, did you read the information in the links about GedComs and GedCompare that is in the Help menu? If not, go through those and try to upload a very small GedCom and get it through the GedCompare process and then upload another just a bit larger and do the same thing. It will go much quicker than uploading a GedCom containing hundreds or thousands of profiles.
