title: svn client doesn't work after upgrading to 1.7: working copy is too old
body: <p>I was using VisualSVN client and server on local machine + MS Visual Studio for a while.</p>
  
  <p>Today I decided to upgrade tortoisesvn to the latest version (because it popups every time that never version is available).</p>
  
  <p>After that I can not commit/browse history etc. from VS. tortoisesvn reports such error:</p>
  
  <p><code>Working copy "C:\pathtorepository" is too old (format 10, created by Subversion 1.6).</code></p>
  
  <p>How to fix my problem? Should I rollback tortoisesvn from 1.7 to 1.6?</p>
