torrents "stopped"

[side]

I am a beginner using a MACosX and bittorrent by a guy named Loweonstern (sp?).

I was dowloading about 4 or 5 torrents the other day and went to download one more and they all were listed as "stopped". I pressed the play button where the torrents were listed in my client and they all chekced existing files, then stopped again.

Finally I got a notice from something else, not the torrent files/client, that my disc dirve was full, so moved stuff to another disc. then tried to restart the torrents, but they just check their existing files and then come up as stopped. I think I must be missing some key restart knowledge. Furthermore my disc, when I later counted file size, should have had about 6 gigs left-- it was never really full.

I could just erase everything and start again, but I want to know what happened, and how to restart.
Also I have this Lowenstern Bittorrent, and also Azureas on my computer, but when I download a torrent I only have the option of opening it with Bittorrent, not Az.

I do not understand thesse computers!!

OK, I erased all the torrents and paritially downloaded files, and tried to start again from suprnova.
Now, I try to dnld a torrent from supernova and my dnld box comes up saying "cannot create a file".

???

Does anyone understand what my computer is doing?
