  <p>I also did something weird.. i think i did check for updates every startup or everyday.</p>
  
  <p>and now it is showing all these errors and not opening up:</p>
  
  <pre><code>Warning - could not install some modules: Bootstrap - The module name   
  org.openide.util.lookup was needed and not found. Upgrade - None of the modules  
  providing the capability org.openide.modules.ModuleFormat1 could be installed.  
  Upgrade  - The module named org.openide.util.lookup was needed and not found. File 
  System API - None of the modules providing the capability

  named org.openide.util.lookup was needed and not found. Startup - None of the modules 
  providing the capability org.openide.modules.ModuleFormat1 could be installed. 3 
  further modules could not be installed due to the above problems.
  </code></pre>
  
  <p>And two options "Disable Modules and continue." and "exit".</p>
  
  <p>Pressing anyone closes the ide. Also last time when ide was working and installed that plugin it was validating other plugins and i exited during that part.</p>
