Paypal trouble~

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.
