I get Unknown FS type 'fsfs' after restoring repository

I restored my svn repository from backup after a hard drive crash. I just installed TortoiseSVN 1.4.3 and when I try to check out from the restored repository I get
   
      Error: Unable to open an ra_local session to URL
      Error: Unable to open repository 'file:///C:/dean/svn.repositories/src.repos'
    Unknown FS type 'fsfs'
   
  I get the same messages when I try to import the repository.
   
  I believe the repository was created with svn version 1.2.
   
  Do I have to do something like creating a new repository and then restoring the backup into the new repository?
   
  Thanks.
