Dancing Stage Max - Dance Master Mode

[Thimy]

Ok, I'm doing the Dance Master missions in DS Max, and there's one mission still locked.
I can't reach the (X-19) and I was wondering if anyone had done it.
I already bought all the information hints in the shop and found all the extra arrows.
Can anyone help me ?

Unfortunatly Thimy I'm as stuck as you are. There are lots of missions I've still yet to unlock, many of them X missions.

Could anyone help?

My boyfriend has unlocked it doing shit, now it's all unlocked. =)

I can help you, just tell me which ones are left. ^^
