Ah, thanks for the replies. My computer is a bit of a mess at the moment. I'm in Bali on my laptop, which came with Windows 7 plus free upgrade to 8 and 8.1. Earlier in the year I installed Windows 10 with the Insider Program, but after too many gliches returned to Win 7. Unfortunately I now only have Win 7, I can no longer use free Win 8. Now, for some reason, my laptop refuses to install Win 7 SP1, which Paint.net 4.0 needs. So thanks for the 3.5 version, I'll install when I get home.

This doesn't show up under Effects. I have re-downloaded and replaced the .dll file, but nothing works.
