okie, this is what i did:
I reinstalled LED Killer back to my phone, found the notification queue. To ensure it will not blink on me again like my last few tries, i called myself, dismissed the miss call; put my phone to sleep with Slide2Unock, wake up the phone.....everything seems to be fine.
So I turned the phone completely off, and turned it back on, it started to blink .....check the notification queue, it's not there, so I went to LED Killer folder, clicked on "MortScript" file, and then "Install" (for some reasons I had to click on "MortScript" first before I run"Install" file).
After clicking "Install" from LED Kill folder, it worked again and the notification queue is there. To make sure it's really working, I repeated what I did earlier (calling myself and such), and then turn off the phone. And repeated few more times.
So now, my LED is not blinking (now that I said that, it'll probably blink on me again

)
