Unable to output file from fluorescence spectrometer (.td)

Hi
I've done a experiment on a fluorescence spectrometer (not the one I usally use) , and I recieved the output in a .td formate. I asked in the lab and a post doc told me the he used spekwin32, to read the data. When I came home I downloaded this program but I'm unable to open the files of interest. Tried every possible way to open them.
I would really love to get down on the data already to night, so if anyone got any alternative programs or any hints on how to use spekwin32 to open .td files then please, feel free to help :D
