We need more info on your system. The error referring to the "Required" folder however strongly suggests there is an issue with OpenGL or MediaCore, meaning something is not configured correctly on your system in terms of hardware acceleration with the graphics card. This also would affect certain CoDecs, so removing third-party stuff like CoDec packs is also advisable.
I do have a media core folder inside of the AE directory. Do you think I have files missing from the required folder?
It was working fine yesterday morning, but just started crashing out of nowhere. I can't see how my hardware is all of the sudden not compatible.
I have a NVIDIA GeForce 310 graphics card
DAC Type: Integrated RAMDAC
Total Avaliable Graphics Memory: 4095MB
Dedicated Video Memory: 512MB
Let me know if there is any other information you need.
I have now tried several different things, including going through the OpenGL troubleshooter on the adobe website.
I uninstalled all the plugins, fonts, deleted AE files etc. I then opened a new user on my PC and it worked! But when I tried opening it for the second time it came up with the same error message.
This happened straight after I installed all the Cycore FX plugin, so I repeated everything as before and opened a new user account. I didn't install anything and like before it opened up the first time, but the second time it crashed with the same message without me having changed or installed anything!
So to summarise:
A new user account in windows allows me to open AE once, the second time it crashes.
Should I just leave AE open all the time? That seems to be the only thing that works!
I was having the same issue. Make sure to check out your Event Log in Windows.
In my case I had this error:
Faulting application name: AfterFX.exe, version: 10.0.1.19, time stamp: 0x4c785da6

After uninstalling this capture driver AE loaded just fine.
My boss found a fix for this problem:
Go to C>Users>(your user name)>Appdata>Roaming>Adobe>After Effects>10.0 and rename thefile "Adobe After Effects 10.0-x64 Prefs.txt"
to "Adobe After Effects 10.0-x64 Prefs_old.txt" Might need to show hidden files for this.
Then open After Effects - it will create a new preferences file, and should open fine.
