As previously stated by someone else in this thread, I can't drop the mission or enter the instance so I can submit the recording. Anyone have a fix for this?I
Talk to the Romulan Civilian at the Mountain Pass transporter pad. He gives the mission to enter the instance. It is a daily mission and can be completed once every 20 hours. If you've done it less than 20 hours ago, the Romulan Civilian will show how much time you have to wait when talking to him. All instances on New Romulus unocked through the reputation system are dailies. So if you forget to submit a recording, or hail D'tan (in the final instance after gaining tier 5 rep) you can just try again the next day.
Having the same issue, still can't drop this to at least start over.
You have to submit the recording after viewing it in front of the shuttle at the end of the mission. These missions are dailies and can be done once every 20 hours. Talk to the Romulan Civilian next to the transporter pad at the mountain pass zone to take the mission again (or see how much longer you have to wait before you can do it again).
