They ignored me 2 times said to look at fourms. lol help full i know.

Hi, i am lvl 11 sith murader and after i trained to use my second light saber i had to fly back to korriban on the shuttle so i could go to korriban orbital station. But the thing is every time i try to take the shuttle back to orbital it says "you cant do that right now". Please help i haven't played in a week and i just want to find this out. Am i bugged or do i need to do quest to leave. Cause i have already quested in korriban orbital my class quest is in that area atm actually.
