I copied some magnet link to BitComet to download. BitComet seems to be able to find some Long term seed for the magnet I copied and downloaded some data.
But after I restart the computer. The download data (about 1.x%) drop back to 0.1%
I cannot keep my computer on all the time until I download the whole torrent. As I turn off the computer at night.
BitComet version 1.71 (64 bit)
I attached the screenshot of BitComet before and after of restarting the PC. And a sample magnet file in .txt format.
