title: The keyref 'ruleSet_202' does not resolve to a key for the Identity Constraint
body: <p>I'm developing a really  large InfoPath form for SharePoint List. After I had to restart my computer the file became corrupted somehow and I don't know how to open it. Here's the error message I get from InfoPath when trying to opent the file.</p>
  
  <blockquote>
    <p>InfoPath cannot open the following form  The
    form definition (.xsf) file contains errors.</p>
    
    <p>The form definition (.xsf) file contains elements, attributes, or
    structures that are not valid.</p>
    
    <p>Error details: The keyref 'ruleSet_202' does not resolve to a key for
    the Identity Constraint
    '{http://schemas.microsoft.com/office/infopath/2003/solutionDefinition}ruleset_name_key'.</p>
    
    <p>Line 2145, Position 3 
    --^</p>
  </blockquote>
  
  <p>I changed .xsn extension to .cab and extracted all the contents. I looked into the manifest file and saw that Line 2145 is actually the last line of the document. I can not find error in it, nor near by.</p>
  
  <p>Help pls</p>
