Skyfactory 2.5 Help!

[SunnyTheFireDog]

So I downloaded Curse launcher, then I got the mod pack, it is SK 2.5, then my Minecraft launcher starts, I click play and then I get this:

 

[19:08:46] [main/INFO]: Loading tweak class name cpw.mods.fml.common.launcher.FMLTweaker

Can anyone help? this is really annoying.

I think you should use FTB Launcher and not Curse Launcher and please next time post the topic in the Sky Factory section.

Also try removing your java arguments if you have any specified to see if it works then.
