Modular Bosses - Help Loading into MC

[Jarubell]

My son wants Modular Bosses, I installed the Forge Installer, I downloaded two versions of Modular Bosses, both 1.8. 

did the %appdata%, found .minecraft but there was no \mods folder. Made folder, moved .jar files into it.

Started Minecraft, tried things but I'm now lost. 

 

Have I done something wrong or are there settings I need to change.

 

Thank you,

Super_Cooper's Dad

Oh, I think I downloaded the wrong version of Forge. Just dl'd Forge1.8.9 and now it sees the files but it says something about same named files.

 

Forge Mod Loader has found a problem with your minecraft installation

You have mod sources that are duplicate within your system

Mod Id:File name

mb: Modular-Bosses-Mod-1.8-SandWorm.jar

mb: Modular-Bosses-Mod-1.8.jar

 

Do I have to delete one?

I think you should only have one of each mod in the mods folder, so yes, delete one of them.
