Can't download TBC client

I'm using BitTorrent to download the client from Warmane's website. I click download and it opens up BitTorrent and choose the folder where I want it to download. I get an error message in BitTorrent, screenshot is below.

Note: I am using Windows in Parallels on a Mac.

Any help would be appreciated, Thanks.
