Generating TAL failed! [C041]

[Zak_F32]

Hi guys, trying to flash my iDrive firmware to enable fullscreen following a guide. 

I'm up to the part that requires you to Calculate a TAL and get the following error

Generating TAL failed! [C041]

DetailInfo must not be null for ECU ECUId:FEM_BODY_0x40

I've checked the VIN across on the FA data and the VIN is correct with the car, the car is connected to E-Sys 3.30.1 via ENET cable selected Connected via VIN.

Does anyone have a solution to this problem?

Thanks,
