title: TortoiseGit 1.7.8: "Couldn't load this key" on "sync" or "pull"?
body: <p>When I try to use "Git Sync" and then "Pull" I get the error: </p>
  
  <blockquote>
    <p>Couldn't load this key (unable to open file)</p>
  </blockquote>
  
  <p>It then tries to proceed with the pull and I get this error:</p>
  
  <blockquote>
    <p>Disconnected: No supported authentication methods available (server sent: public key)</p>
  </blockquote>
  
  <p>This has happened only since I upgraded to 1.7.8.0.  It was all working just fine before.  I can successefully pull using gitbash so I know I can connect.  </p>
  
  <p>I am not sure what changed, or what I can do to fix it.  Please help!</p>
  
  <p><strong>ADDITIONAL STEPS</strong></p>
  
  <p>I went to the the GIT folder and used gitbash to check git remote -v and received:<br/>
  .puttykeyfile<br/>
  origin git@github.com:{name}/{repository}.git (fetch)<br/>
  origin git@github.com:{name}/{repository}.git (push)</p>
  
  <p>I think that is correct.</p>
  
  <p>I checked the putty key settings in tortoisegit.  I have two entries:</p>
  
  <ol>
  <li>.puttykeyfile - which just has .puttykeyfile in Remote </li>
  <li>origin - this appears to have all the correct information in Remote, URL and Putty
  Key</li>
  </ol>
  
  <p>When I load the key in PuTTYGen it has the ssh-rsa 1024... key fingerprint.</p>
  
  <p>pageant.exe was running, but isn't now, but it still doesn't work</p>
  
  <p>When it was working before, I had on git folder in the same folder as my key.  Now I have 3, but none of them work and it doesn't seem to work if I create a new git folder with a single repository and key.  I don't know if it affects the results, but wanted to share that just in case.</p>
