安卓虚拟机无法运行!

在安卓官方网站下的eclipse配置好的!但是虚拟机无法运行!!
出现下列错误!

[2013-09-09 11:27:09 - test] Android Launch!
[2013-09-09 11:27:09 - test] The connection to adb is down, and a severe error has occured.
[2013-09-09 11:27:09 - test] You must restart adb and Eclipse.
[2013-09-09 11:27:09 - test] Please ensure that adb is correctly located at 'D:\adt-bundle-windows-x86-20130729\sdk\platform-tools\adb.exe' and can be executed.

任务管理其杀掉adb,cmd重启下adb试试,要么就是看看是否有进程占用了5037这个端口
