I downloaded the game too yesterday (had no PS on this computer) and BitComet couldn't connect to the tracker so I just used one of the mirrors (Xordan's) and everything was ok. Took a bit longer though (around an hour now and I remember downloading the installer as a torrent in less than 10 minutes once when it was freshly released).
And just a little note: Afterwards I had to run the updater around 10 times or more and wait quite long until everything was updated properly. I got various error messages from "Couldn't read updaterinfo.xml.bak" through the OpenAL32.dll error to "Incorrect md5 checksum of client.zip (not sure if this was the name of the file), reverting file". The updater crashed around 5 times. But now everything is ok and I can get in-game just fine

. The only thing I did was making a copy of updaterinfo.xml and renaming it updaterinfo.xml.bak and then just clicking the updater and waiting (and keeping an eye on the updating process, of course

). What I'm trying to say is:
don't give up if you have problems in the beginning.
