【Android】Android Emulater can't be started

After not normally  closing Eclipse & AVD,  I restart Eclipse & AVD then got an emulator error "emulator: ERROR: the user data image is used by another emulator. aborting".

Survey some solutions:

1. Use "adb kill-server && adb-restart-server"                                      (Not work)
2. Delete C:\Documents and Settings\@USER@\.android\avd  .lock files   (Work)
