When I install DownloadPsychtoolbox in the matlab, appears this error:

  

svn: E170013: Unable to connect to a repository at URL 'https://github.com/Psychtoolbox-3/Psychtoolbox-3/branches/beta/Psychtoolbox'

  

I searched this URL and realy doesn't exist. So, why the program is trying to acess this page?

What I must to do?

  

Thank you!!

Works correctly, just tested. Assuming you have the latest DownloadPsychtoolbox from our website, it must be some network (firewall?) problem on your side. Retry again later, or try downloading from a different network.
