In order to sync this application with your computer, you need to plug in your Wireless Sync Dongle in a USB port and press Continue. After that, open the Option menu and select from there the Proxy settings (you can select one these settings: don't use a proxy server, automatically detect proxy server, or you can select to add a proxy server) that you want to use. If this doesn't work, I suggest you to stay in touch with the developers and ask them about this problem.
