Reply to upgrading my VCI to 1.4 - not working anymore!

Hi,

i have a VCI100SE which i bought on the website, with firmware 1.3

I have the upgrade kit and used this USB to serial cable: http://www.moxa.com/product/uport_1110.htm

After sorting out the problem with the port, i follow every step from Ean's video, til the software says the flash has succeed.

But now i plug the VCI on my computer, it doesn't light on, doesn't respond, looks absolutely dead.

It is really complicated cos i don't know which step i did wrong.....
please help me
