Topic : svn: E160006: Invalid revision number '-1'  I have recently come across this error when I installed the svn client on my machine. I have the latest version of tortoise svn client on my local machine.

Conclusion : Try to download the tortoise svn of same version as of server and it seems to work fine without any problem.
