Paypal trouble~

So I'm trying to charge NX from paypal and everytime I click buy under any of the prices,and then payments by paypal, another window opens saying "There was some error during login, please log in and try again" What is this about?

This is the first time I'm using paypal, so I'm not sure if I'm supposed to have my paypal account under the same e-mail as my maple account or w/e else that could be wrong linking the accounts together.

Any help is appriciated~

My maple account and paypal account are under two different emails and I've successfully purchased NX through paypal. I know Nexon's anti-fraud verification system can be dumb sometimes and reject purchases. There were a few times where it said I needed to verify that my billing address was correct because their system was saying that I was "misinterpreting my billing location" when I didn't even change anything from the first time I purchased. It started working after a month then went back to not working, and is now working again.

You can try check here for more explanations as to why it's not working.

Thanks, I'll see what comes of the situation after this :]
