After effects project file issue

I bought a project file but when I open it I get errors missing “particular” “element” "optical flares"
I dont have the said plugins and I can’t seem to make the text edits on the project.
could I be doing something wrong?

If Particular and Optical flares are missing, then there could be a pre rendered version of the same included in the zip, If Element 3D is used then there wont be any pre render, Just post the link of the project, So that it will be easy to assist

What Stroke said. But if there isn’t a pre-rendered version, then you will need those plugins to work with the template. It should have mentioned that under the ‘required plugins’ on the item page.
