Will i get sick from this A1 steak sauce ? (read the description) please help !?!?!?

Ok, so i just had steak for dinner and i had some A1 steak sauce with it . It says on the label "refrigerate after opening", does this mean that i should have refrigerated it before i ate it ? It was in the pantry and unopened, and i just opened it and ate it . Was i supposed to refrigerate it first ?!?! Will i get sick ?!?
