Transmission

Since this morning every completed download from various trackers ends up as .part files. I don't understand what's going on, of course I can play the files in VLC but I can get them onto my ipod. I repaired permissions and reinstalled VLC, I even tried rolling back to the last stable version and nothing worked. I can't remember doing anything that would have caused this.

I'm on a Snow Leopard Mac.

Any help would be appreciated.
