Well, it would help to make the video public....
First warning is no problem.
Second warning: You have a missing font, find it or use another.
Third warning: either you didn't download the associated footage, our you did not put it in the right directory, or it's not been included in the project.
From the look of the rest of your video the second footage isn't required to make the project look like their sample. The missing footage names tell me that they are just textures and a vignette. Something you could easily replace.
You always get what you pay for when you download free templates.
