Korea, Asia realm Can't Access now

hello, i’m warcraft3 old user.
i love WC3, so i played very long term this game.

thesedays, warcraft 3 Battle.net can’t access now.

it seems strange post ACC(old id) can’t access.
if log-in tried, message ’ errors ’ and can’t log-in.

only new acc can access korea, asia realm.

so many players are can’t play theirs old acc , except only new acc.

please solve this problem…

I heard after 3 months or 5 of inactivity it gets deleted.
