Just paste your key into a new notepad file and save as key.bin
I don't think that works,
well it doesn't i just tried it myself,
what you need to do is open the lite-on ofw for your drive, (from the LT firmware pack) in the source section of jungleflasher,
tick the advanced view box, (Next to thespoof source button).
click on the drive serial tab at the top,
double click in the window bellow the drive serial tab, a new box will appear,
self explanatory, put the details from your drive's stickers in here then click ok save it where you want as "myofw.bin
then open the "myofw.bin" in the target section.
then click on manual spoof,
then type or copy/paste your key where it says load key.bin,
click check,
then click ok,
that will put your key in the right place,
then flash as you normally would.
