Hi, I'm using GenArts Sapphire 1.10 with Premiere Pro 2, and some of the effects just won't work. When I drag them onto a clip, they just come up in the preview window as a red matte. Many other effects work fine though. I don't think it's a registration problem, as it's not a watermark that comes up.
Previously I've had to uninstall and re-install the program, and even then it will work once and then 'red screen me'.
