make sure that the FIRST line of the file starts with CP START ACCOUNT - no blank lines, no nothing else. Otherwise your fn will be an empty string resulting in what you've quoted/observed above.
Or to accommodate and skip any lines BEFORE the first CP START ACCOUNT:
Code:
awk     '/^CP START ACCOUNT/ {if (!(n%20)) {close (fn); fn=("F" ++i)}; n++}
         fn {print > fn;}
        ' file
