You're at Level 5 (550/600) right? If so then that's all there is at the moment! There are extra quests to come - they're written and ready but it's a matter of having them added and going. Hopefully it's within the next month or two that there will be more! 

Im having this problem too

But now i know why im not moving forward.
So theres no way to move forward  except to wait for the add-ons?

Correct. A lot of us have been stuck at level 5 (550/600) for a while now. It is a two person team running this game as well but thankfully, there is other stuff to do whilst waiting for more quests to come out.
