Sorry Bob but with the check instructions, it falls always in error I try :svn checkout http://clickclick.googlecode.com/svn/trunk/ clickclick-read-only error Server sent unexpected return value (400 Bad Request) in response to REPORTrequest for '/svn/!svn/vcc/default'
Try to use another SVN client, e.g. something like SmartSVN: http://www.syntevo.com/smartsvn/index.html (the tool is "wizard" oriented and it's very easy to use)
Also try to checkout to a clean new directory. Adrian.
