Basic Comsol-Matlab Problem

Hi,
I am new to using comsol with matlab so i apologise if this is an obvious question.
As a first step I am simply trying to save a model as a .m file and then run it in matlab. When i try to do this is get the following error message in matlab:
Undefined variable "ModelUtil" or class
"ModelUtil.create".
Error in play1 (line 10)
model = ModelUtil.create('Model');
I am running comsol 4.2.0.228 on a mac, and matlab R2011b (7.13.0.564) both 64bit.
The model is an extremely simple one, just a 2D bimetallic cantilever with a fixed constraint at one end being subjected to a temperature.
Does anyone know what this error message means, and if its a common problem how i can fix it?
Are there any tutorials on using the Matlab LiveLink, comsol seem to provide them for most other modules but i couldn't see any?
Any help is much appreciated.
Joe

Could it be that you didn't start "COMSOL 4.2a with Matlab", but just Matlab alone? You didn't specify that in your post. Because if you just start Matlab, it doesn't import the Comsol libraries and you'd end up with an error message like you described because Matlab won't have a clue what "ModelUtil" is.
Like most modules, the Matlab Livelink ships with a "User's Guide" and an "Introduction to LiveLink for MATLAB". You'll find a simple tutorial in the latter document.
