I loaded up my version of Minecraft (forge 1.12.2-forget1.12.2-14.23.5.2847) and ran into this problem with CCL. I continued to do some research and found a post related to this issue and found a comment saying to delete the config instance of CCL. I continued to delete the instance and then tried loading it up again but I was given the same error message. Any suggestions or help would be great.
