I left Fopnu on overnight, and this morning all of my downloads are at 99% and stuck. The status is alternating between Downloading and Finding Sources...
Three of them are one MB short of the total size. They are all .mkv files. I've tried restarting the client, and am using v1.3.3 on Windows 8.

the frozen downloads finally finished when i started up fopnu today, in case anyone else is having this same issue. seems you just have to wait.
