How on earth one can finish this test?? I am getting loose my mind. The instructions went so fast and i cant follow it.

Please give me some idea on how to finished it.
Im using wiki in doing this quest.
I also want to ask, according to wiki the place to dance on to is in
diagonal but in game its directed North, East, West and south(like a cross)

Please help me. Any help would be appreciated.

Edit: Also as quoted from
http://ragnarok-guide.com/the-sign-quest-part-i-crumbs-of-sobbing-starlight/ it says:
The next test is the dance test. The trick to the dancing test is to set your effects to on and go to the spot that made an effect like the ‘hide’ skill. Also, click the tile at the
corner towards the center, for it will already count. Having an Increase AGI status will also help. I passed this test with only one try doing this trick. If you fail, talk to Dearles again
What does corner towards the center??
I was doing this dance test for more than 3 hours now.

EDIT: I still dont get the success msge from the examiner

I dont understnd how and why I didnt get successful inspite of that there are times that I was abled to "unhide" with "sound" all. And also I noticed that there are variations of where the "hide" will pop up especially on the later half of the test.
May I ask the GM help?

please
