help My modpack that worked 2 hours ago, is now crashing everytime I try to load it

[madscientist10]

I had tried adding 2 mods to my current modpack and made a new zip so I wouldn't mess with the working one.  It didn't work of course, so I used the old zip that was working to update the modpack back to its slighty older version.  Now that one doesn't work either, even thought I never messed with that particular zip file.  Here is the crash report:

Your CreativeCore is quite outdated, I suggest updating that. https://www.curseforge.com/minecraft/mc-mods/creativecore/files
