In the utility section of the NI-SCOPE driver is a link to the HWS file API.  It looks like a folder with waveforms on it.  This will allow you to read the file.  You can convert it  to a text file using the standard LabVIEW file tools.
Alternately, if you are into real pain, you can download the 
HDF5 toolsets from NCSA and create a C program to do the same, but I wouldn't advise it.  HDF5 has a very steep learning curve and the internal structure of the file is fairly complex.
Let us know if you need more help.
