Thank you for your post.
It's possible that the iCam app settings on the Android phone have gotten into a bad state.
On your Android phone, go to Settings -> Applications -> Manage Applications and then choose iCam and the "Clear Data". Then try connecting again.
Also, please check to make sure the Droid Bionic is connected to the same router as the computer running iCamSource. This behavior could happen if the phone was connected to a different router on the same local network.
