ziadomran wroteI did something... Thanks anyway.. The problem was that: utorrent didn't want to open.
I went to : C:\Users\UNFORGIVEN\AppData\Roaming\uTorrent
And deleted everything, then I opened utorrent.. It worked!
I've lost everything I was downloading.
Deleted everything?? :facepalm: you could have told us...I would have advised you to keep the torrent files in that folder, and delete everything else. Then you can add them back, and all your downloads would be restored. Anyways, if the data is still there (I'm guessing it is), then you can just redownload the torrent files (.torrent), and add them back, and choose their download locations the same as where you were downloading them. This will cause uTorrent to check what has already been downloaded, and that way those downloads would be restored. Good luck!
