Make a new AE project file. IMPORT the old project file into the new one. Save it. Quit AE. Restart your machine. Open the new AE project file. It may sound weird, but you should be good to go.
In addition, you could wave a dead chicken over your head in the light of the full moon. But I don't think it would help.
It could also be an incompatible Element 3D version, but we don't know that.

The file was worked on AE CS6. But I removed cs6 It's CC2015.0 now.The plugin is Trapcode-Form (But I am not sure how many plugs in this file.)
