Re: “Already Installed.”
And the error message?
In your bbPress’ config.php, did you set $bb->domain and $bb->path or did you set $bb->uri (the easier method that bbPress 0.8.2 allows)?
Try setting
$bb->uri = 'http://www.bqtrademark.com/bbpress/';
in your config.php and remove from that file any lines referencing $bb->domain or $bb->path
