title: BI Publisher - Fail to load and save data model
body: <p>Started BI Publisher about a week ago.
  When working on a new data model, about one or two queries in, I get this error when I try to save:</p>
  
  <pre><code>Failed to load servlet/res?s=%252F~developer1%252Ftest%252FJustin%2520Tests%252FOSRP%2520Information.xdm&amp;desc=&amp;_sTkn=9ba70c01152efbcb413.
  </code></pre>
  
  <p>I can no longer save my data model.
  I tried deleting my queries, logging in and out, turning machine off and on, but no luck.</p>
  
  <p>I'm currently resolved to saving all of my queries locally in notepad.</p>
  
  <p>I can create a whole new data model and it will save fine, but then after two or three queries the same thing happens.
  What's going on and why would anyone design such a confusing error message?
  Any help would be greatly appreciated. </p>
