I spent the day looking for some solutions in the forums. Then I downloaded the programs and files from the photo below. I then ran the zbootloader to update Njoy32. He stopped halfway and after that hell began. Now it does not work anymore. I tried to use the other programs, install the firmware "gladiator_vkb_v1_85_b" but nothing. Any light please?

I read that it was just plug and play, but I've been here for over 8 hours and nothing to make it work.
ps: I'm Brazilian, so excuse me for writing.
