The internal encoding of the raw data has changed, so I do not think any 
current reader will handle it.  You can probably get it by loading the 
data with ParaView 0.6 and then saving it in another format (such as 
.vtk).  Then use ParaView 1.4 to load the .vtk file and save it as a 
.vtp file again.
