Lvl 50 Beastmaster cant advance after crash

I joined my nephews game as a lvl 50 BM, he was 20 lvl’s lower and went into the social menu and hosted a game in S3000. When we arrived the game froze on 2nd round in splitscreen. Now when I log on with lvl 50 BM it only shows first 3 planets even though all quests are completed. So now i can’t get to planets other than first 3 and I can’t advance because all quests are done. SO my lvl 50 is only aloud to go to Pandora, promethea and Athenas. How do I get to go back to other planets now to fight better bosses for loot
