I'm trying to download a movie and as first step tried to open an existing torrent file.

When clicking on "open" and double clicking the torrent file (for example "World____s_Greatest.Dad.2009.DvdRip.Xvid__1337x_-Moursi.5178267.TPB.torrent" which was downloaded from thepiratebay), I receive the following message:

"Unable to open torrent file /C:/Users/ToshibaUser/Documents/Torrents/World____s_Greatest.Dad.2009.DvdRip.Xvid__1337x_-Moursi.5178267.TPB.torrent : The filename, directory name, or volume label syntax is incorrect.
The torrent is probably corrupt or is not a valid torrent file."

That has been fixed in 3.3rc1
