Have you completed any Imperial City quests already? There was a progress-blocking issue whereby if you had completed an IC quest because it was shared to you by someone else, but had not completed City on the Brink, then City on the Brink would bug out. This is fixed on Live but there may be some residual effects of it still causing issues. If that's the case, then you should reply to Support with the name of the quest in IC that you have already done.
Besides that, the next step to try is to abandon the quest, log off for fifteen minutes (which allows the area to do a soft reset), and then try again. You may also try taking the quest from Captain Rythe at the Northern Morrowind Gate, instead of General Nesh-Tan, to see if that makes any difference.
It actually can't (or shouldn't) happen to anyone any more, as they fixed it so that you can no longer accept a shared quest if you haven't done City on the Brink already. I think it's the fact that you completed the Arboretum quest before completing City on the Brink that is your problem.Have you completed any Imperial City quests already?

Thank you so much for your reply Enodoc.
I have just tried both way but unfortunately they didn't worked. I think it is kind of a propblem which should be resolved by in game masters. Do you have any reccommendation about how to proceed?
By the way... I have completed only Arboretum's quest. Then before taking another quest, I have helped my friend to complete IC's final quest. He tried to share the quest with me however couldn't do that and that progrees may cause this bug.
What should I do... This can happen to anyone
