No, I did not! Take a look at the beginning of the file
http://bioexploratorium.pl/ljw/cpmd/nvt/cont.nve/4mdnve.inp - it reads:

&CPMD
  MOLECULAR DYNAMICS CP
  RESTART WAVEFUNCTION COORDINATES VELOCITIES NOSEE NOSEP ACCUMULATORS LATEST
  TIMESTEP

  EMASS
    400.0
  MAXSTEP

  SUBTRACT COMVEL ROTVEL
    2500
  TRAJECTORY XYZ SAMPLE

  ISOLATED MOLECULE
