After loading the avs file into Megui and start the encode, I get the following error log:

I used the encoder setting present x264: Unrestricted 2pass Anime_Toons HQ

Can anyone help me out?

Solved the problem. no need to answer.

I put in the latest version of the x264.exe and it works fine now.
