If you have Bridge 1.0.3 installed you may wish to run it and select updates… from the Help menu so that you can select 1.0.4 to download.
This update promises faster performance and improved security and should be downloaded.
There are versions for the mac and pc. If you have a version of Bridge earlier than 1.0.3 then you will need to download 1.0.3 before updating it.
You can download updates for Bridge and Photoshop here, Adobe have “improved” the site which as far as I can see makes it slower and less easy to use than their old design, if it aint broke….
