PVT Accurate as of 2016?

Hello, I just took my LVN NCLEX exam here in CA on Feb 23rd 2016 at 2:00pm. I am starting to lose my mind. In California, you don't receive your results for 6 weeks. Quick results are not available here. I don't know if I passed...I felt the test was very hard and I'm sure I was missing a lot of questions during the exam. Today is Friday Feb 26 and I just tried the PVT trick at 10:15pm. I used an expired credit card and submitted the payment. This is the message I got:

" Our records indicate that you have recently scheduled this exam. Another registration cannot be made at this time.

What does this mean? Does this mean I passed? I am very skeptical and I think I still failed.

Please help me. I don't want to get excited then find out I failed. Does the PVT trick even work anymore? How accurate is it? I have been studying since the day after I took the test because I felt I failed. Idk what to do. -Angela
