title: Upgrade TortoiseSVN 1.8 issues
body: <p>I upgraded <a href="http://en.wikipedia.org/wiki/TortoiseSVN" rel="nofollow">TortoiseSVN</a> to 1.8 from 1.7.12 on Windows&nbsp;XP. After that it asked for upgrading of the SVN format.</p>
  
  <p>I tried upgrading, but it keeps asking and the command produce no error. I tried to checkout a new copy from the server, and it keep asking to upgrade.</p>
  
  <p>I reverted to 1.7.12.</p>
  
  <p>How can I fix this problem?</p>
  
  <p>I don't know what happened, but it seems it started upgrading the repository correctly. Is it maybe a problem with the cache?</p>
