close eclipse, in the Task Manager, kill all adb and emulator* processes.
start eclipse, run your application, wait untill the emulator starts. If you have the problem, your application won't be started, there will be the bare emulator.
In eclipse, select Window->Open Perspective->Other->DDMS. Switch to DDMS perspective. If you have the problem, the list of the devices will be empty.
In the Devices tab, in the drop-down box, select "reset adb". In a short while, the emulator must appear in the devices list.
Following that, switch back to your Java perspective and run your app. Everything must work fine for the rest of the session.
