NIK filters problem

Hi Everybody,

1. I've installed the NIK filter collection into Photopaint X6.  The filters show up under EFFECTS and under PLUG-INS in the tools dialog.  Initialize at start up is checked.
2.  I can open a filter dialog and make changes.  Then I click on OK in the filter dialog.
3.   However, the changes do NOT appear in PP X6.

Does anyone know what else has to be done to get the changes to appear in PP X6.
