VKB-SIM

Installed the above grip on a Gunfighter MKII base and now only 4 axis work by moving the handle.
Tried to upgrade the firmware via VKBDevCfg-C Version 0_91_7_3 but it will not recognize the files: _BlackBox_GF_MCG_Ultimate_Twist_v2_02_0.vkb and more.
What can I do here..

Thanks, David

Your firmware version is current, software is not; please download the latest from here and try again following step by step this guide; the file you will have to flash is not the one you mentioned, but this one: _BlackBox_MK2_GF_MCG_Ultimate_Twist_v2_09_0.vkb .

Thanks, at last I am flying again what a relief.
