I'm was using ReiNX on 8.0 Firmware and it works fine, but when I switched to Kosmos latest Payloads, all the games thats was preciously installed is not working, It said " Unable to start software, Return to HOme button and try again" (it's the same mgs when trying to play the games without the paypoad injected), the Homebrew apps is working fine and I can install games...Anyones know why the games are not working ?
