title: visual studio 2013 update 4 - javascript highlithning stopped work
body: <p>i am using "VisualStudio 2013 Update 4 (CommunityEdition)" everything works fine till last week.
  Then i noticed that my JavaScript highlighting stopped working which is embedded in my HTML code.</p>
  
  <p>It works fine and I never had problems before. Till last week, then it suddenly stopped working :/
  I don't know why... i didn't changed something on my computer (no updates, no new software, no hardware upgrades) - it just stopped working :(</p>
  
  <p>This thinks I try to solve the issue:</p>
  
  <ul>
  <li><p>every step did in this thread
  <a href="https://stackoverflow.com/questions/10970305/how-can-i-get-user-type-c-sharp-syntax-highlighting-working-again-in-vs-2012-rc/11003979#11003979">How can I get user type C# syntax highlighting working again in VS 2012 RC?</a></p></li>
  <li><p>reinstalled VS2013</p></li>
  <li><p>reopened my project  and  created a new project</p></li>
  </ul>
  
  <p>Nothing solved the problem... it still don't work...</p>
  
  <p>At the moment i really frustrated, because i don't know why it stopped working and i don't know what i should try else to fix this problem...</p>
  
  <p>Maybe somebody had the same problem and can epxlain me what i can check to fix this issue?</p>
  
  <p>Thanks in advance,
  vipex</p>
