I had Mathematica installed in
[drive]:\winaps\wnmath22
and the Integrate package was located in
[drive]:\winaps\wnmath22\Packages\Preload\Integrat
The Definite.m was in that directry, but I still got the error, Even
after reloading.
So I tried reloading again and this time I installed to
[drive]:\wnmath22
Now the problem is gone.
