I was using Kosmos ver. 12.1 with firmware 7.0.1 when I was unable to launch the game after updating MK11 to 1.0.3. Beforehand on MK11 1.0.2, I could load the cheats when I was using Kosmos, but after I couldn't get the update to work on that I updated my firmware to 8.0.0 and used Kosmos 12.1.2...
