Hi, I got the same exact message, nothing about contacting the board. This means you passed!! Don't worry all is well. If you want to just verify that you passed, pay the $7.95 to get the quick results. Congratz!!!
I took my NCLEX-PN exam on tuesday April 15th and got the "good pop-up" (Our records indicate that you have recently scheduled this exam. Another registration cannot be made at this time). I paid $7.95 to see my unofficial results. The Pearson Vue trick worked!! I passed!!
