unable to flash for new grip

[taq511]

I like to change from my SCG Premium-R to MCG Pro Twist-R

With the VKBDevCfg-C I choosed the existing grip. After my first try it says now VKB Boot NJoy32 platform v00.56
I go to the Bootloader, and it automatically tries to read/write data and there are error messages. On Top it says "Device not ready"
I choose _Blackbox_Mk2_GF_MCG_Pro_twist_v2_00_7.vkb and press Flash it.

The Log say now:

CPU_ID fail
Error write Data: Numbers
Error read Data: Numbers
device not ready aborted

than it goes scrolling without stopping:
Numbers: Device connected
Error write Data: Numbers
Error read Data: Numbers
Numbers: Device connected
Error write Data: Numbers
Error read Data: Numbers
on and on and on.
I'm unable to close the program, it will just post Unable to write to zconfig.ini
I deleted the VKB device in the device manager and started after computer restart the VKBDevCfg as Admin with no difference.
Need help and ideas. What shall I do?
Cheers
