IP Unban/Reactivating Account Troubles

I don't know where to put this so Imma just put it here. Feel free to move it if it doesn't belong here.
----------------------------------
Can anyone help me on this? So anyway, this is what happened:

1. I saw the "Big Bang Tespia" Notice on Maplestory website
-thinking at least one of my many mules account have to be chosen-
2. I slowly log on to all my accounts
3. After logging on to 30 account I got IP banned
-Non of 30 account got chosen to be in Tespia ---SADLY!-
4. I fill in the IP Ban form to get my IP unban
5. Waited ONE WEEK -- Got my IP unban
6. Log on to my account
- Got the message saying I have to reactivate my account-
7. Clicked on the "Sent Reactivate Account to email"
8. Log on to my email
-Clicked on "reactivate Account" link
9. Log on to account
-It tell me to change my password-
10. Changed my password
-I got that message "Successfully change password" or something like that
11. Go to nexon website and log back in
12. I got that stupid message again saying that I have to reactivate my account
13. I REPEAT Step 7-12 over and over again until I got that message saying "you have exceed the changing password limit" --or something like that

I don't know what to do now. I can't submit nexon a letter, since I can't even log on to my account with that stupid message "Reactivate you account"

Anyone else got this problem beside me?
