I suspect your FT to be damaged. See if is correctly writen and try again.
You can try directly write with EEWriter. If not work, uncheck "Autodetect VID/PID" and replace 24 with 20.
If not work, FT defective or Atmega defective. 90% FT defective. Can try write Atmega with USB ISP programmer, the communication can be interrupted by an altered firmware.
