I can't upload my DNA data (from FamilyTreeDNA) to gedmatch. If I try to upload a csv, gedmatch says the file is too small and cannot really be my results; if I try to download the results again from ancestry.com I get as far as the button they send to 'confirm download request', and it then always tells me that the link has expired or is invalid (even though it is supposed to last a week, and I never leave more than a few minutes). What do you think is happening, and how can I get round these blocks?
