Mapsource Doesn't See New Product

I have CN6 installed with CN8 upgrade. I'm using the latest version of
Mapsource v.6.11.5. Both CN's work fine and I can select either one from
the product selection drop down on the toolbar. I just bought Fishing
hotspots east and it says during installation that it sees an existing
Mapsource installation and that it will be modified to accept this product.
It finishes installing and when I go to the Mapsource application, there is
no product installed accept the CN's. If you go to Help About Product Info
again it only lists the CN versions. Any ideas?
