I'm sorry, but I don't really understand your question.
Stick to using the latest version of Flash Magic, so stop using 1.73.
Can you get the device into ISP mode?
How many times were you able to program it?
Did you change the boot vector at all?
How are you entering ISP mode?
I need as much detail as possible.
