The only way to know is to make a good starter and see if it does anything.
According to the wife (who actually worked in a lab at UPenn with yeast!) you should be ok as long as the container is still sealed and they were keep within a proper temperature range. She said the they jsut might need some more time to get going, but that you should be alright in the end.
