Nexon[KR] Registration Problem

Hello! I'm trying to register for Nexon Korea, but I keep getting this error. I've been trying for a few days now, but it still won't work. I always get the same error. I've tried a bunch of different KSSN's, one under 14, one 17, and one much much older, but they all get the same error. And yes, the captcha is correctly entered. I just have the error box covering it, so sorry. If anyone could help me with this problem it would be great. I've seen no one else get this besides me, so I thought I'd make a new thread... Heres a picture of the error.

When I translate it over google translate, it says "Membership is the progress" or something like that. I'm so perplexed. Any help would be appreciated!

a friend of mine had the same problem but once i tried it, it worked :x
try entering a phone number with 3 and then 4 digits for both entries.
thats the only thing that i can think of right now.
