You dont need it. I would remove it and add the "ZP_SniperArena-Pure: Zeroping SniperArena" mutator (some sort of special NGZ web interface since its called that I guess).

Btw, do NOT add the "sniperarena" mutator too, only "ZP_SniperArena-Pure: Zeroping SniperArena"

Make sure that you dont have both the ZPPure7E and ZPPure7G versions in your system folder, because they will both show up in the interface, you cannot tell them apart, and only the one added as serverpackage will work.

Edit:

The way you have it set up now with "Pure: ZeroPing" and "sniperarena" does work, but its a lot less accurate than "Pure: Zeroping SniperArena".
