Hi Yue_Hong,
You can still continue using PhoneGap Build 3.3.0 which is the default and the latest version. If you see the "Build Queued" message, then just quit and relaunch Dreamweaver. You will see the success/failure states of web apps. Alternatively, you can also login to build.phonegap.com and get your webapps.
Thanks,
