I tried your code (see below) and get no error message. So the problem
seems to lie on your end. Maybe get rid of all matwrite files manually
and install the package again.

J.

. clear

. set obs 5000
obs was 0, now 5000

. set seed 1234

. gen x = uniform()

. gen y = 2*x + invnormal(uniform())

.
end of do-file

. matwrite x y using c:\matlabfile, replace
(note: file c:\matlabfile.mat not found)
file c:\matlabfile.mat saved
