Done I keep crushing on start up.

Iv done everthing i could and i still cant get on SF2 or AG2 becuz of this plz someone help. here is the log

 

minecraft opens and starts to load all the stuff but when it on 2/5 of the load its stops java binary on mod:Cfoh Core

 

Firstly I would recommend trying the MyM launcher. If you already are using that run a force update by right clicking skyfactory 2 in the launcher and selectic "hard force update"

 

ok thats what everyone has said and i did 5 times over took it completey out of my pc.

 

But how would he fix it?

 

even after doing everthing everyone has said to do.

 

Yes

 

When in doubt through it out....

Have you tried a fresh install of the launchers themselves?

Also what folder are you loading/ saving every launcher to?[DOUBLEPOST=1432701787][/DOUBLEPOST]Questions:

Are you using an AMD?

And do you you have optifine/ Fastcraft installed?[DOUBLEPOST=1432702012][/DOUBLEPOST]Ok this looks like an Optifine bug, if your using an out dated version.
@KillMeNowPlz3

 

If you added Optifine, its not useable for SF2 some people had Optifine added in the mod list so they crash when its loading.

 

Its the version of optifine, not optifine itself.
I have tested and if you pick the correct optifine version for the forge version being used, then you fine. But most people cant or dont do this. And its why we dont recommend you using it.

 

For some reason, I used the lastest 1.7.10 Optifine and it won't work.. But for SF2.3, I use the lastest 1.7.10 Optifine and it works...

 

This is most likely due to a Forge update.
Click on "changelog" on the Optifine site. see which version of forge each version of optifine uses.
ALSO use standard version of optifine if you must use it at all. the Ultra version is a crash fest

See here: https://optifine.net/changelog?f=OptiFine_1.7.10_HD_B7.jar

this is the reported problem and version they fixed it
OptiFine 1.7.10_HD_B7
- updated to work with Forge loading screen
- compatible with Forge #1395
(27.04.2015)

 

Just me using Fastcraft, Optifine, Vein Miner, shader's and never crashed by this mods?

 

A lot of people use these mods.... thats not the issue, The issue is the versions they are using.

 

Optifine I think I use the last version, and the others I use from MyM launcher..
