Arduino IDE blink code not compiling , with no specific error message

Hi , I have been using arduino since 3 years with very satisfactory results , one fine day it happened that I uninstalled the software and reinstalled it , since then even the blink code in the basic examples is not getting compiled , further it shows no error message , please help . I had deleted both the library sketch folder and the Arduino15 folder while uninstalling , and yes I recently had a Windows(10) update. Compiled on arduino ide version 1.6.0 , works perfectly , what's the deal here??

Please do this:

  • File > Preferences > Show verbose output during: > compilation (check) > OK
  • Sketch > Verify/Compile
  • After the compilation fails you'll see a button on the right side of the orange bar "Copy error messages". Click that button.
  • Paste the error messages in a reply here USING CODE TAGS (</> button on the toolbar).
