There appears to be an issue with the Matrix class of example
data. I am able to load the first example data set as follows:
ExampleData[ExampleData[class][[1]]
where class is one of
{"AerialImage","Geometry3D","LinearProgramming","Sound","Statistics","TestA=
nimation","TestImage","Text","Texture"}
But this fails when class is "Matrix" with the error message you
indicated. And since "Matrix" is one of the classes returned by doing
ExampleData[]
I see no reason for this to fail.
And FWIW, I see this using
In[1]:= $Version
Out[1]= 7.0 for Mac OS X x86 (64-bit) (February 19, 2009)
on Mac OS 10.6.4
