I've recently finished a 1:30 hour long project,
The project files were scattered in different directories so in order to save the project for future use I used the
"Pack Project Materials" to save the project to a new unified directory.
I've then deleted all the old directories assuming that all my project files should now exist in the new directory.

However to my surprise when I tried loading the project from the new directory all the "Titles" and "Particles" I've used in the project were showing without the animation part in them only dots instead of the animation
(The attachment is showing what "Star trail 2" particle looks like in my movie)
Example for particle used in the movie : "Star trail 2"
Example for titles used in the movie : "Cool glass lower 1", "Cool glass lower 2"

Any help with fixing this problem would be appreciated
