If you type Sphere in the Effects and presets search field and you don't find it and it's not under Effects>Perspective, then re-install AE. It's part of the package and that's the only place you can get the free version. There is a paid version that has more capabilities available from Cycore.
Thank you, it comes up but then says 'missing'. I'll have to re-install I think, thanks for your help

Actually, we've been including the full CycoreFX HD bundle with After Effects since After Effects CS6, so you no longer need to buy the full version from Cycore separately.
