point cloud las file import

the nysgis clearinghouse has LAS file for down load, 

attempting to load the las file to convert to POD,  i established my geocoordinates to be on state plane nad 83 east,  when i try to bring in the LAS file 

it prompts me for "you must seletc a GeoCS from source,  not sure what to assign here, there is not additional files with the LAS file

i have successfully done this in the past with no issues,  not sure if the las files data has changed

any information would be help

thanks
