GamepadBlock suddenly not working propaly + updater won't work

  • I use the GampadBlock for my RaspberryPi project using RetroPie. I got it to work and all was well and good until I turned on the system and the arrows and A button didn't work proply. It continualy pressed right until I press left, pressing left makes you sometimes scroll right and other times does not work, the A button only works sometimes i press it and up and down don't work in the settings menu, but on the games list. It basacilly became unusable. This just happend suddenly, it was working fine earlier that day.
    I have verifed that it is not physical issue with the cables or anything and have lates version of RetroPie.
    Rebinding the keys does not help. Some buttons can't be bound because they are "already taken"
    Trying to fix the issue I tried to update the firmware once again, but then I get this message and it don't work.

    C:\>petrockutil-windows-amd64.exe gamepadblock update COM4
    Downloading the latest firmware

    Press the RESET button on the GameapadBlock to activate its update mode.
    Press 'Enter' to continue...
