st: option nullok not allowed

Hello everyone,
I am trying to run survival analysis on the dataset I created. The
data is censored and fairly large. -stset- works fine, but I get
option nullok not allowed
stata(): 3598 Stata returned error
when attempting a basic Cox Proportional Hazard regression via -stcox-
Can anyone tell me what you think the problem is (as r3598 does not
provide any clues that I can understand)?
