A) Did you set the quest as your active quest first?

B) You should be prompted to pick between the normal Disruption mission and the Hidden Messages version.

If you got the inbox message from Ordis about Olympus, have the quest active, and it still doesn't offer you the alternative mission version, then it's probably bug report time.
