Happen something similar to me, i had those mails with gear from companions ( one from ashara) i was still doing my class quests in Alderaan when suddenly, no more purple quests, i went around looking for anything even back to ship to reenter planet from spaceport nothing. loading screen kept saying i was about to convince the jedi to give the relic....searched the entire planet and nothing, went to Taris and i had some class quests.......all up till atacking the republic spaceport then it stopped without any indication where to go next......
