Issues with Bayes net toolbox installation

Hi all,

I am very new to Matlab, so I am sorry if I am asking a simple/already answered question. I am trying to install a Bayes Net Toolbox for Matlab, I have followed the instructions from this link: http://bnt.googlecode.com/svn/trunk/docs/install.html But, I am getting the following error message:

Error in genpathKPM (line 5) X = 1; Q = 2; Y = 3;

Output argument "output_args" (and maybe others) not assigned during call to C:....

and if I try to make a Bayes Net (as specified in the tutorial -- http://www.cs.ubc.ca/~murphyk/Bayes/usage.11dec01.html#basics), I get the following error message: Undefined function 'mk_bnet' for input arguments of type 'double'.

Can someone tell me what the issue is?
