Just found a way to make the Delorme plugin work for my windows 10 laptop. Went to Internet Explorer..(actually it opens in "Edge"). Opened Geocaching.com. Then click three little dots in upper right corner and selected from dropdown options to "open with Internet Explorer". Then the downloader started working again the way it used to....at least for about 10 minutes till IE crashed & had to re-boot again.... hope that helps...
