TrakSat 2.80 21st century dates

I was trying to use my old TrakSat 2.80 program to check on
some ancient results, and find that it doesn't seem to handle
dates past 2000. I.e., the date field calls for yy, presents dddd,
and tries to throw current dates back to the start of the last
century, judged by the display.

Does anyone know if there's a way to work around this?
