关于在Eclipse中创建安卓小项目 的问题

Eclipse中创建Android小项目时，出现报错信息：

 [2012-12-06 07:52:33 - Sample_11_3] ------------------------------
 [2012-12-06 07:52:33 - Sample_11_3] Android Launch!
 [2012-12-06 07:52:33 - Sample_11_3] The connection to adb is down, and a severe error has occured.
 [2012-12-06 07:52:33 - Sample_11_3] You must restart adb and Eclipse.
 [2012-12-06 07:52:33 - Sample_11_3] Please ensure that adb is correctly located at 'D:\Program Files (x86)\android-sdk-windows-1.6_r1\platform-tools\adb.exe' and can be executed.

adb路径是对的，而且也试过adb-kill server和adb-start server,依旧出现这样的报错信息。

要怎么解决这个问题？
