Can't Install FML on ATLauncher

[sirj0k3r]

Hello!

 

I'm trying to install FML (version 12.18.1.2098-universal) on my Vanilla Instance (version 1.10.2) via ATLauncher and I'm not being successful.

 

Here's what I'm doing:

 

 

After clicking "Add", I make sure I click "Enable Mod" on the mod window that comes up before this one.

 

Here's the crash report (also can't enter any Single Player World):

According to the ATLauncher Forums here, the method is downloading FML Universal for the current version and add it as a Jar Mod.

 

If they explained it right, I must be something wrong, just not the installation part.
