16.marras.2012 10:49:49.219: LOG: User Prompt - Title: Sector Erase Failed Message: Failed to erase the memory sector. The new data being flashed likely conflicts with the ECU's persistent data. The persistent ECU data can be replaced by erasing the entire flash memory before programming. If the ECU may contains a non-standard flash memory chip, it could be causing the erase to fail.

Press Yes, to erase the entire ECU flash memory and restart the flashing process.
Press No, to skip flashing this sector and continue the flashing process.
Press Cancel, to abort the flashing process.

WARNING: Only erase the entire flash memory if you have a good communication connection with the ECU. If flashing fails after erasing the entire flash memory, it is likely the ECU will no longer boot, and will have to be reflashed on the bench using boot mode. This software does NOT support boot mode. Result: CANCEL
16.marras.2012 10:49:49.219: USER: Writing ECU flash memory failed.
16.marras.2012 10:49:49.400: USER: 100% complete. 

What should i do to get this work again?

Do you have the car hooked up to an external power supply?

I reinstall drivers and Nefmoto software. Now it's working like before.
