Can not download realm to PC

I can not download my 1.5gb realm to my PC in rev 1.20.30. I have plenty of disk space. The download opperation shows the file size transferred to the 1.5gb size, then just  hangs. I looked at the disk location where the realm downloads are stored but a new folder was not created but the date on an older one is updated. Was this one overwritten? if so can I play it locally?
