John,
Please try this 4-call version of the same race (same file name, different format):
TU111708.RAC
It is produced by the in-progress development version of the RDSS2 major Update 2.1 (late Winter?). If you go to the Classic Programs Forum, many of the examples worked by Bill V earlier this year make use of that interim (unpublished) version to export to 4-call programs. RDSS2.1 is just not ready for prime-time yet, but it will be within not too many more months.
Ted
