Eclipse and Android SDK stopped working

Question

I have been programming using eclipse and the Android SDK for a while now, and they stopped working suddenly today. What happens is whenever I try to open them, either from the start menu or folder, the splash/loading screen comes onto the screen for about a second, and then disappears. This has never happened before, and I can't seem to find anyone online with a similar problem. I restarted my computer, re-installed both the SDK and Eclipse, and still no luck. The only thing that may be affecting it is that I recently installed the Leap Motion software and SDK 2 days ago, and I haven't used either Eclipse or the SDK since then.

I'm running windows 8 and I already installed a JRE when I first got this computer. Thanks for any help. I you want me to post any more information about the problems just tell me what and how to find it. Thanks for any help.

UPDATE

I tried to add -clean and the same thing happened, and the same thing happened when I ran eclipse.exe from command prompt. No error message came up.

I re-installed java, and now it works perfectly! I think I may have messed up Java when I stopped an update in progress (which I forgot about until this morning. Sorry) Thanks everyone for your help.

Try downloading the Android Studio, much better than Eclipse. http://developer.android.com/sdk/installing/studio.html

And, for simulator, I recommend using Genymotion http://www.genymotion.com/

much much faster than android simulador
