SVN on root url makes repository listing 403 forbidden

Question

I recently installed Collabnet SVN on my windows server. However, I hate the /svn at end so I moved it to the root domain. However it's now giving me 403 forbidden.

Here's my config

<Location />   
   DAV svn
   SVNParentPath "C:\csvn\data\repositories"
   SVNReposName "CollabNet Subversion Repository"
  AuthzSVNAccessFile "C:\csvn\data/conf/svn_access_file"
  SVNListParentPath On
  Allow from all
  AuthType Basic
  AuthName "CollabNet Subversion Repository"
  AuthBasicProvider csvn-file-users
  Require valid-user
</Location>

Is there any way around this?

Edit- Error log:

[Fri Sep 16 23:27:00 2011] [error] [client 192.168.1.253] Could not fetch resource information.  [500, #0]

[Fri Sep 16 23:27:00 2011] [error] [client 192.168.1.253] Could not open the requested SVN filesystem  [500, #720003]

access log:

192.168.1.253 - admin [16/Sep/2011:23:27:00 +1000] "GET / HTTP/1.1" 403 202

The rest of the config file is really big, but it's the bog-standard from collabnet.
