here is th eimportant part: "To load a VI from LabVIEW 3.x or earlier, you must use the LabVIEW VI Conversion Kit, which is available free of charge from National Instruments. The part number of this kit for Windows and Macintosh is 776874-03. VIs from UNIX must be transferred to a Mac or PC where the VI can be converted to LabVIEW 4.0 and then transferred back to UNIX. The LabVIEW VI Conversion Kit is not available in the online catalog. Please contact the National Instruments Sales Department directly to request this free conversion kit." good luck Dan
