PODcreator Crash when Creating

I have some Trimble point cloud data that PODcreator seems to have trouble with.  I have several file formats none seem to work.  The LAZ crashes PODcreator each time the export is attempted a .pod and .tmp are created but the are not useful.  Also have .las files that were exported from Trimble Real works that PODcreator reports file conversion error message.  This is true for several data sets we have from Trimble Real works.  Does PODcreator not handle Trimble data sets? 

The data sets are for a relatively small area, i.e. inside of culvers,  but the .laz file is 2.5GB.
