Psychtoolbox is locked? - Psychtoolbox and svn issues

Hello. I'm currently having issues with Matlab, specifically in regards to updating Psychtoolbox. Earlier I had begun the process of updating by typing in the requisite command. However, my internet had cut off and the update stopped. After regaining my internet connection, I waited to see if the update would resume but it hadn't. I closed my laptop assuming I could update it all again later. Well, I have attempted to restart the update to no avail as I am met with this error message:

UpdatePsychtoolbox(' C:\toolbox\Psychtoolbox ')

About to update your working copy of the OpenGL-based Psychtoolbox-3. Will execute the following update command: svn update "C:\toolbox\Psychtoolbox" svn: E155004: Working copy 'C:\toolbox\Psychtoolbox' locked. svn: E155004: 'C:\toolbox\Psychtoolbox' is already locked. svn: run 'svn cleanup' to remove locks (type 'svn help cleanup' for details) Sorry. The update command failed: svn: E155004: Working copy 'C:\toolbox\Psychtoolbox' locked. svn: E155004: 'C:\toolbox\Psychtoolbox' is already locked. svn: run 'svn cleanup' to remove locks (type 'svn help cleanup' for details)

??? Error using ==> UpdatePsychtoolbox at 169 Update failed.

Somewhere in there is the option to perform "svn cleanup" however when I enter that command in MATLAB I am met with this:

">> svn cleanup ??? Undefined function or method 'svn' for input arguments of type 'char'."

When I typed in, "svn help command" I was met with:

">> svn help cleanup ??? Undefined function or method 'svn' for input arguments of type 'char'."

My questions are:

1. Why is my Psychtoolbox now locked? 2. How do I unlock it? 3. What is svn? 4. What am I doing wrong?

Still new to MATLAB.

"svn" is the Subversion version control system.

Try

!svn cleanup

I had the same kind of issue. I had to run Matlab as administrator to solve the problem.
