Missing Effect - Form

I purchased "Clean Blue Stardust Glow Particles and Flares Space Logo Reveal Animation" by Kalfasso. When I open the project it states that the effect "form" is missing. How do I resolve this.

I have emailed the seller as well but hoping it is something the community can help me solve quickly.

Form is a plug-in from a third party that you would need to purchase separately. It is part of the Trapcode Suite from Redgiant.com

sometimes artists also mention that you will find pre-rendered version in main download in such case there's no need to purchase additional plugins but for long run you better buy it
