VKB-SIM

I just bought the Gladiator Pro MkII, used from a friend. When I plugged it into USB, it ran normally. However, after turning off the PC and after some time, when I reconnected the computer it was no longer being recognized by Windows 7.
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.

Try to use up to date zbootloader (1.15) from here https://drive.google.com/drive/folders/0B1WRiD1czmcHMVBEcVQ0dndyNG8?usp=sharing
It is usable for modern firmwares. And last VKBDevcfg (0.87.98).
Also you can try fresh firmware for Gladiator from here https://drive.google.com/drive/folders/19YOG4AxSs_m35KYdK2YDkh3lSJNvtf2m.
