I'm getting...

"Plug-in: 'Sony Track Noise Gate' failed to load. Please make sure the plug-in is properly installed.
Plug-in: 'Sony Track EQ' failed to load. Please make sure the plug-in is properly installed.
Plug-in: 'Sony Track Compressor' failed to load. Please make sure the plug-in is properly installed."

...on loading a previous project.

What do I do to fix this?

Thanks
