Minecraft Launching Problem

HELP!!! When I'm done launching my Minecraft, it appears nothing but I read something in the Development Console like this "at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)" I kept trying it again everyday but it appears nothing still. I'm using 1.7.2 and up. Thank you for reading this...
