[amelia] Every observation is coded as missing

I am trying to load SPSS datasets into AmeliaView. I started with small datasets that include just a handful of variables (5-7) to see how the program works. But everytime I load the datasets and 'Summarize Data', AmeliaView tells me that all the observations are missing for the variables, which is definitely not true in the original dataset. What am I doing wrong?
