The error message is telling you of a problem with a third-party effect plug-in. I'd start by asking the makers of the Neat Video plug-in for assistance.
Exactly the same thing's happened to my on my 2010 iMac - I upgraded from Snow Leopard to Lion when installing AE CC, and now I get the same Neat Video error... bizarrely on a separate machine here which went through the same upgrade process, it still works fine.
Apparently, the search method you used had certain limits.
Please directly delete that file:
1. Launch Terminal.app (/Applications/Utilities/Terminal.app)
2. Enter (or copy&paste) the following command into the Terminal window and press Enter:
sudo mv /usr/local/cuda/lib/libcuda.dylib /usr/local/cuda/lib/libcuda.backup.dylib
The command must be entered in one line.
After Enter is pressed, the system will ask to enter your admin account password.
That should be it.
Its something to do with the CUDA drivers. Hope it helps this fixed mine
This solution worked for me.
