Cannot log in on certain accounts, characters

After today's Unscheduled Server check I try to log in on my Wild Hunter's account, maple turns black for some seconds and the message pops up saying "Trouble logging in? blablabla".
I tried logging in on another account, I could log in on 6 of the characters there, but when I try the last one, it crashes.

I've had this problem with 2 accounts for about a month now and its driving me chinchillas. I sent a ticket and hope to get an answer from Nexon within one business day (no i was joking about the one business day)

Same thing is happening to me. Also, whenever I try logging in on the website, it says the server application is currently experiencing difficulties processing the page.
