check here, there's a link to post directly to gumi's support what's the issue. http://forums.gumi.sg/forum/news-boards/232487-advisory-july-25-known-issues

better yet, send in a support ticket for them to attend to your friend directly.

posting here is useless as this is fan-supported wiki, not related to gumi.
