Just purchased ACP Expert. I received 2 registrations along with the email explanation for that. Both Scheduler and ACP Obs accepted the 2nd registration number successfully. I neglected to even attempt the Pinpoint registration until now. I am using the Pinpoint registration Applet. However it will not accept the registration. I even used both registration numbers. As well, I modified the date to that which was shown in the registration email. Everything appears to be running perfectly, however. But everything I am doing with the software is utilizing simulators exclusively.
