I just loaded Windows 10. It wiped out all my Prism2 logs I had previously. I reloaded the the desktop on my laptop. When I went to download my logs off my Petrel (about 60 of them), about 1/2 downloaded, then I got an error message. After that, it refused to load any more of my dives,... kept giving me an error message. I uninstalled/ reinstalled the Bluetooth dongle, I uninstalled/ reinstalled the Desktop, with no success. Any ideas why? What can I do?
