Hello, I just recently purchased a P4. Have had it out one time, would like to fly more but the machine wants a firmware upgrade. I have installed the Assistant software for the P4, connected the Bird to it. The software sees the Bird, however I can never get a download list. I have tried the update on my MBP, wife's PC, and daughters PC. All of them do the same thing, I never get a list of Firmware files to selected. I tried contacting DJI, however they have not responded in 2 days. I would like to get this figured out, because I do want to keep this Bird. Installing Firmware should be a smooth process. Thanks in advance for any and all help.
