An I/O error occured for torrent in windows 7 x64

[wokitoki]

System: Windows 7 Ultimate 64 bits
4GB RAM, 500GB Seagate SATA disk.

I google it, and nothing. Chkdsk, uninstall and more, when I uninstall everything I lose all the torrents I have in the queue.

2 torrents with 99.9% say that stupid error, and I cant do a shit, now I lose all the torrents(8 with around 75% completed).

The disk dont show errors and I dont know what to do now, I try everything I find in the forum and google(try old versions, news version and more).
