server Crashing on startup Sponge/forge/Ae2

[Keaton]

Hi all, I am setting up a FTB Beyond server (just to do some tests on) and need sponge for it.

I have installed Forge correctly and added Sponge to the mods, when it starts it gives me this error 

(First pic is with Ae2 on and trying to start the server)

 

When I remove Ae2 and Ae2 Stuffs, the server launches further than the previous error.. but still gives me another error (another pic below)

Yes.. but the second error thats telling me about Ae2 being missing.

 

If I don't remove it then I get the first error (one with sponge).. with Ae2 removed I dont get that error.
