Emulator not starting up

Latest download of everything running on Vista. I had everything working, emulation working, etc., but at some point it stopped and I had not messed with the SDK or anything, still slogging thru the tutorials...

Now when I Run | Run the emulator does not start up on the screen. I think it happened sometime after I tried Run | Debug to see what that would do (which was nothing) but that doesn't seem like it should cause this problem.

The console 开发者_开发知识库shows was showing a launching of a new emulator, and the emulator responding with the GNU message and that's the last output. Now after a restart, the console is showing nothing, just "Aptana JavaScript Scripting Console Started". The Task Manager does not show the emulator in the Process list.

I tried running emulator-x86 -avd my_avd and I get: C:\Android\android-sdk\tools>emulator-x86 -avd my_avd qemu: linux kernel too old to load a ram disk C:\Android\android-sdk/platforms\a ndroid-7\images/kernel-qemu, C:\Android\android-sdk/platforms\android-7\images\ /ramdisk.img, qemu=1 console=ttyS0 android.qemud=ttyS1 androidboot.hardware=gold fish clocksource=pit android.checkjni=1 ndns=1

Is the installation corrupted somehow?

BTW, I installed the whole SDK and NDK, but I'm reusing Eclipse from when I was doing some webOS development on the Palm Pre.
