error when running NLO event

An error occured when I was trying to run a program following :
(My madgraph is lastest version)

define lep = e+ mu+ ta+ e- mu- ta-
define nu = ve vm vt ve~ vm~ vt~
define V = w+ w- z
generate p p > lep nu V a [QCD] @0

output WVANLO
( I have modified some content of "run_card.dat", such as "50.0 = bwcutoff" , "0.0 = ptl ! Min lepton transverse momentum"
   "10.0 = ptgmin ! Min photon transverse momentum", "0.3 = R0gamma ! Radius of isolation code" . But I don't think these cause error)

launch WVANLO ( --------> error occured like below)
