Since your post refers to Photostory, rather than a video product, I have moved it to the correct area, where it is hopefully more likely to be seen by users of the specific software.
I don't own this app but, assuming it "works" in the same way as other Magix products, do you have any tab, menu or other heading called "Effects" or similar? Are these effects shown there?
It did not show up automatically. What I did was hit "Additional Effects" and then "Scan." PhotoStory Deluxe found the twelve add-ins. I had to close the program and restart. This time PhotoStory Deluxe showed the three HitFilm packages with the twelve add-ins! A happy ending! Glad! Whew. Lance
Please Help, I have tried everything. I have installed, reinstalled the Hit film Light show pack and the Hit film color explosion several times. I have placed it into different folders to know avail, When I hit "Additional Effects" and then "Scan" it still says no plugins available.
