title: This client is too old to work with working copy
body: <p>Everywhere I go on google I get the same answer to this problem but it is the wrong answer for me. Originally I installed Subversion 1.5.6 for windows (i run Windows Server 2008) on my server and i made a repository for a project. Then I used a Tortoise client version 1.6.X on my laptop to update the project. Everything was hunky-dory until I tried to use a post-commit hook script (i am updating folders in wwwroot on commit to reflect changes on a web page). I got a message to the effect of "This client is too old to work with working copy 'XXX'".</p>
  
  <p>So I uninstalled the SVN client on my laptop and removed the repository from the server. I then made a new repository on the server from scratch and installed TortoiseSVN version 1.5.6 thinking if the client version is the same as the Subversion on the server then they should play nice. After i downloaded the repository on my laptop again and reinstalled my hook script I get the same message...</p>
  
  <p>It is quite painstaking and disruptive to have to keep obliterating my repositories and reinstalling my client to find ones that co-operate through trial and error. I see no reason (and can find none online) as to why the repository would argue if both TortoiseSVN and my server Subversion are both 1.5.6.</p>
  
  <p>Is there anyone out there that can give some insight as to why I would be getting this message? Perhaps even someone who could let me know what version of TortoiseSVN I need to use in order for my Server SVN 1.5.6 to not complain. My hook script works from the command line on my server so I know it's not it's fault. Thanks in advance.</p>
