Hello JaredB1219,
From the error log it say's you have a duplicate mod as shown here:
AppliedEnergistics{rv11.c} [Applied Energistics] (appeng-rv11-c)
AppliedEnergistics{rv11.c} [Applied Energistics] (appeng-rv11-c.zip)
In a typical Voltz server you would have just one which is:
AppliedEnergistics{rv11.c} [Applied Energistics] (appeng-rv11-c.zip)
I recommend removing the other one as it is not needed:
AppliedEnergistics{rv11.c} [Applied Energistics] (appeng-rv11-c)
If you need anymore help, please reply back!
It would help if you had your server, a picture of your mods and coremods to further check into this if the AppliedEnergistics removal of that one duplicate mod did not work.
