As stated in a previous post I am having a problem with my Godox TT685F's. Possible problem is Godox web site. Emailed Godox, no response. If I down load the G1 or TT685F firmware or if I try to open on their web site, instead of an executable file I am asked how to open the file as a text, spreadsheet or HMTL I can pick either one and get an error. Can anyone go onto the Godox site and please confirm they can open either file or are they getting the same as I get. I am using Win10 via parallels on Mac book Pro. Did not have this problem when I updated my X1F transmitter. Thanks for your assistance.
