In the help for the software it says "If you have the hardware unit, then you can find the serial number in the unit" How do I get it? How is it formated? I have a GMC-300E Plus. In the menu under "Other" is a Serial # F48*** When I enter the hole number I don't get any reaction from the software.
I tried to register using Windows 10 and GQ GMC Data Logger V5.56. I get same problem. I have set Windows inbound and outbound rules to allow this software to go thru Windows Defender Firewall for executable file located at %ProgramFiles% (x86)\GQ Geiger Counter Data Logger PRO\GQGMCounterPRO.exe I still cannot achieve registration.
