updating PTB after matlab

Hi to all,  
   
I just recently updated my version of matlab and wanted to run UpdatePsychtoolbox.&nbsp; I wnet to the dir and typed

> \>\> UpdatePsychtoolbox

and got this msg:  
   
 

> \>\> UpdatePyschtoolbox

??? Undefined function or variable 'UpdatePyschtoolbox'.  
   
 

> \>\> UpdatePyschtoolbox.m

??? Undefined variable "UpdatePyschtoolbox" or class "UpdatePyschtoolbox.m".  
   
(This after typing ls to make good and sure that I was in the correct dir.)  
   
I then typed it in all lowercase, so:  
   
 

> \>\> updatepsychtoolbox

and then got:  
UpdatePsychtoolbox(' /Applications/Psychtoolbox ')  
   
??? Undefined function or method 'RemoveSVNPaths' for input arguments of type  
'char'.  
   
Error in ==\> UpdatePsychtoolbox at 80  
oldPath = RemoveSVNPaths(genpath(targetdirectory));  
   
   
Any tips on how to update my copy of PTB?&nbsp;&nbsp;  
   
Cheers,
