I'm running Windows Home Premium x64 and the very latest version of Bittorent. I grab a few magnet links, and later, I either pause them or stop them before quitting the program itself. When I run Bittorent again, the torrents I had been working on have disappeared. The files are on the hard drive, but as far as the program is concerned, it didn't do anything before. I am able to get the magnet links again and do a "Force Recheck" to tell the program how far it had gotten, but that always takes forever.
