Ok, i make it work, i restore my old Reinx 2.0 folder and files, copy the new Reinx 2.1 + sept folders and choose to overwrite all files, i think there's missing some files inside the zip from 2.1 release, now work's fine, thanks.
Yes, i update the file in the payload menu, delete the old Reinx folder, paste the new from 2.1 release and delete file ReiNX.bin from SD Card root, but got this error message.
