VP-390 Fails When Programming M27C160 Reply

 I have a VP-390 running on Windows 10 on software 4.7.0 and firmware version 17.0.

I have been trying to program ST M27C160 chips, and it always fails after writing a few bytes. I have made sure to Select the chip model in the software before trying to program the chip. I have tried 15 different chips and all of them have failed. They all pass the Blank Check and I can successfully Read the chips. Other types of chips are programming just fine - only the M27C160 chips fail.

Any advice?

 I have always been using the AC Adapter all along with my VP-390.

I updated the firmware to version 23, but it made no difference.　I still can"t get any ST M27C160 chips to program successfully. Any other suggestions?
