Charging two different accounts

I charged two accounts with the same paypal account. What happened was it only lets me charge NX through paypal once a month on either account. I've switched to just NX Cards now. You don't get banned/blocked from my personal experience. But now it only allows me to charge NX through a Paypal account once per month. If I tried to charge it again, it'll give me an error saying that the info I entered is wrong and to check it again.
