Bonjour problem with Documents to Go desktop when trying to sync my iphone

Apparently there is an issue in the version of Bonjour that comes with iTunes 9.1 for Windows or later, which has caused problems for applications that use Bonjour. Documents To Go Desktop uses Bonjour to communicate with Documents To Go for iPad/iPhone/iPod Touch, so the sync will not work if Bonjour does not work. Since the release of iTunes 9.1 for Windows, many users have posted messages about various Bonjour-related issues on Apple's support forum.
I am trying to sync my documents to go files on my 3GS iPhone with my PC files and they recognize each other but won't sync.
