运行程序报以下错误：
[2012-07-21 11:40:04 - ImageGridActivity] The connection to adb is down, and a severe error has occured.
[2012-07-21 11:40:04 - ImageGridActivity] You must restart adb and Eclipse.
[2012-07-21 11:40:04 - ImageGridActivity] Please ensure that adb is correctly located at 'D:\Android\android-sdk\android-sdk-windows\platform-tools\adb.exe' and can be executed.
环境变量没问题，在CMD下指令都可以用。昨天关机之前还没有这个问题，今天开机就不行了，求解~~
你到'D:\Android\android-sdk\android-sdk-windows\platform-tools\adb.exe看一下在不在，如果没有发现的话，那就得重新安装adb。
