Error while reading VTK files in Paraview/VisIt

I have been getting the following error while opening a .vtk file in Paraview:

"Error reading ascii data. Possible mismatch of datasize with declaration."

I am running a simulation on my Mac OS X 10.9.3, and saving my solution files in .vtk format. While the initial solution file (at time t=0) opens perfectly, the above error occurs with the next few solution files. Moreover, some of my scalar variables disappear from the data-set in Paraview. I tried opening the file on my friends laptop, which has a linux OS, and Paraview opens all the files correctly with all variables in place. I noticed a similar problem while using VisIT.

I have even tried to use different versions of Paraview but the problem persists. Could there be a problem with the vtkreader? Any help or leads to solving this issue will be much appreciated.

PS: I have found a similar post on this forum, but no one seems to have replied to it yet: Paraview "possible mismatch of datasize with declaration" error

We really need to see the data file to see what could be the problem. – Utkarsh
This is an example of a file which gives this error: dropbox.com/s/w8gpr42uvy9yh18/sol0072.vtk On paraview I can only see the variables Temperature, Pressure and Velocity, while variables like Density and Mach number are not displayed even though they are explicitly present in the file – rayd
This is another example of a solution file which stores just one variable "convar". I am simulating a linear advection problem. Everything displays well till file no.22, but form file n0. 23 onward (dropbox.com/s/vq8imuhuh5p60io/sol0023.vtk), everything goes haywire. I get a similar error and the range of the variable seems to blow up. Once again I tested this on a linux system and it displays everything correctly. – rayd

Your file declares 70970 points although I think that it has 70971.

Your file declares 140760 cells although I think that it has 140761.
