[Paraview] Reading file series and image stacks in Paraview 3.2.1

[Enkelejda Tafaj]

Hi,

when using paraview 3.2.1 I have problems while reading series of files. 
E.g. when trying to read a file series file_xxx.vtu only the first 
object/file in the series will be read.

The same thing is happening while trying to read an image stack 
image_xxx.png. I need to read the whole stack at once, which was 
perfectly working with older paraview versions (3.0.1).

What I am doing wring?

Thank you for your help,
Enkelejda
