Character Name: LeoPold Problem: I dc every time when I click the button to learn 'shadow shifter' Details: the skill now appears on my 4th-job skill list but its master level is 0, and the option to learn this skill still appears on the window when I talk to the NPC, but I just cannot learn it since I still dc every time when trying to do this. I re-downloaded and reinstalled 2 times but still could not resovle this problem.
