Purchased & Downloaded AE Logo projects

I've purchased and downloaded two AE projects for logos. I've replaced the logo in both with the client's logo. I do a ram preview and everything looks fine. However, after adding the composition the the render cue and render out as a video file (avi) the videio reverts back to the original project with their default logos. I emailed one of the project creators 4 days ago and have not received a response, and Neither help file included with the projects I purchased is helpful. What must I do to get these to work correctly and render out the logos I replace in the project?

Below is the contents of their respective help files

It's really easy to set up:

2. You can also change the background color, the liquid composition logo in "Main" on the layer "Color"

3. The final render 1920x1080 or 1280x720 (25fr)
