    Hi Lois Langehaug,

    Could you please check if you can log into your Pix4D account using this link

    Generally, when the e0702e error occurs we suggest to do the following:

    Solution 1:

    Ensure that your computer's antivirus allows Pix4Dmapper Desktop to connect to the internet.
    Make sure that the firewall is not blocking, via ports 80 and 443.
    Solution 2:

    Disconnect from the internet and launch Pix4Dmapper Desktop. You can reconnect to the internet after Pix4D Desktop launches.
