Psychtoolbox download problem for PC

Hi,
I've been trying to install psychtoolbox on a Windows XP machine that
runs Matlab 7.0.0, but I've been having problems. I downloaded SVN,
rebooted the machine, and then tried to download psychtoolbox. After
10 minutes or so the download fails, and I get the following error:


Command "CHECKOUT" failed with error code 1:
svn: Can't open file
'C:\toolbox\Psychtoolbox\PsychContributed\.svn\tmp\text-base\nc.exe.svn-base':
The system cannot find the file specified.


Will retry now by use of alternative http protocol...
The following alternative CHECKOUT command asks the Subversion client to
download the Psychtoolbox:
svn checkout
http://svn.berlios.de/svnroot/repos/osxptb/beta/Psychtoolbox/
C:\toolbox\Psychtoolbox

Sorry, the download command "CHECKOUT" failed with error code 1:
svn: 'C:\toolbox\Psychtoolbox' is already a working copy for a
different URL; run 'svn update' to complete it

Any help would be much appreciated!


Thanks!
