I found the latest AE 10.0.1 update, installed it. It read that everything installed correctly. Then upon loading up AE, I still get the following messages one after the other:
"After Effects Warning: Failed to initialize mediacore"
"After Effects Warning: MediaCore is not correctly initialized"
"You have at least one output module that refers to a missing ouput plug-in. Please check your Output Module Templates"
The bizarre thing is that before, I had to do a system restore because of my Nvidia Card (which is still not working), I had this same problem but I fixed it when I installed AE updates directly from within the program. Then I was able to import all media files. but now i cannot import any audio or video files!!
