The most usual explanation for a Fatal Runtime Error when you try to run
the program is that there is one or more blank lines (or lines with some
sort of "trash") at the end of the data file. Your data files should be
pure ASCII files (not files from a word processor, unless they are saved as
text files) and must have nothing after the last data line.
One way to check to see if there is anything at the end of the data file is
to open it up in a word processor, such as Microsoft Word, and turn on the
option that shows "all" special characters and spaces. Then go to the end
of the data file and click the paragraph symbol at the of the last data
line. Try to then advance the cursor -- it should go no further. If the
cursor goes further, delete everything that's there after that last
paragraph symbol -- and then be sure to save the file as a text file with
the correct name and extension (the correct extension is .DAT).
If this does not solve your problem, please email your data file to support@assess.com and
we will try to determine if there are other problems
in the data file.
