Anyone able to get Torrex Pro to work not on wifi?

[Fiann]

I'm trying to download a file with Torrex Pro. I got the torrent added and the location selected to save it. I hit start and it just sits and eats battery with the screen on without downloading a single byte of data. I've turned off the only download over wifi option. I'm at work and bit torrent is blocked by our firewall so it's the only option. The file's only about 100 megs in size so I'm not worried about the data use on it. Any idea why this refuses to work?
