Hi,

I have been downloading a number of mods using Minecraft Forge Universal latley.

However, when I try to download NEI and the ChickenCore I get this error message:

Forge mod loader has found a problem with your minecraft installation the mods and versions listed below could not be found Code chicken core minimum version required is 8.6.10.


Here is the log from the launch.

Hey, the reply!

I did as you said, but I then got this crash message:
"There was a problem starting up Minecraft and FML!"

Here is the new crash report:

You downgraded to the 1.4.7 version instead scrolling further down to the Old Versions link.
Also ChickenBones fixed the Problem, so now you simply need to download the latest versions of CodeChickenCore and NEI
