HELP!!! Arduino IDE will not start!!

Hi All,

I am new to microprocessors, but not to loading programs or extracting files from Zip or Tar folders. The problem I have I've never seen before, three days ago I loaded the Arduino software onto my PC and ran it until just a couple of hours ago..NO Problems.
Today, I tried to load a library from GitHub? and had problems so I tried a different library from another site and the IDE GUI froze. The Arduino program would not open so I uninstalled it, rebooted my PC and reinstalled it. Still Will Not Open!

Help, I do not know how to proceed and I am in the middle of an important project build, can anyone help me?

PC running Win7 64bit with lots of RAM and lots of HDD space.
