Android :: Failed To Parse Output Of Adb Version Error

I have the following problem. I was developing in android using the eclipse and android-sdk-windows saved in an folder (e.g. C:androidandroid-sdk_r07-windowsandroid- sdk-windows and C:androideclipse-pulsar-helios-win32). But after i downloaded and installed the eclipse and android sdk again, in the after folder, i got this error message: "Failed to parse the output of 'adb version' " and can't run my application, because the emutaros that starts is not identified by the eclipse, i can't find it into "Devices" tab from eclipse. I found from the net the following http://stackoverflow.com/questions/2260118/failed-to-parse-the-output "Try closing Eclipse, issuing a 'C:UsersMohitDocumentsAndroidSDKools kill-server' command from terminal and retrying. If that still doesn't work, you could try opening Activity Monitor to see if there are any existing adb processes running, and kill them. but i am using Windows XP and i don't know how to use kill-server command from the terminal. I mean in run/cmd there are is no such a command or how can i use the second solution - to open Activity Monitor from Windows XP
