[Paraview] error while loading and animation of vtk files

[naveen kumar]

Dear paraview users,

i have a small problem,

i am trying to visualize the atoms in paraview, i converted a set of lammps
dump file to .vtk format.
if i chose some individual file it works (it shows the atoms)

when i load all the files, while doing animation it closes the paraview
abruptly.

the vtk files are attached with this mail
if i read last file lammps25.vtk it shows the atoms
if i read lammps0.vtk file and press apply the paraview GUI disappears.

what might be the reason?

i am not getting where it is going wrong.
could anyone help me, please.

Thanking you
Naveen
