The chip is not been erased correctly. The software is waiting for "Erased Successfully" signal from the chip, but the chip did not send that command.
There are some possibilities:
1. The chip is not contact well with the PLCC32 socket.
2. The chip is not a good chip. May be poor compatibility.
To find out why, we need a problem chip for testing. If possible, send the testing chip to support@mcumall.com. They will return it to your after testing.

Did you use original USB cable? Try on a good quality USB cable. Shoort and Strong.
Use latest software. |

Did you use the USB hub?
Try to direct connect to the computer and use a DC power adapter.
One possibility is the bad chip. |
