Serial Number

A license grants you ONE serial number
One serial number may be used to activate two computers (Mac or Windows doesn't matter)
One license is intended for one person (ie: you can not give your second activation to another person)
To activate your second computer, run kJams and go "Help->Enter Serial Number" then use "copy and paste" to paste your serial number
To deactivate a computer (say, to move to another computer, or before you reformat your computer), run kJams and go "Help->Deactivate"
Licenses are transferable

Where is my Serial Number license file located?

Your Serial Number file is located in the preferences folder in your home folder.

Mac: <home folder>/Library/Preferences/kJams/kJams Serial Number.xml
Win: <home folder>/AppData/Roaming/Preferences/kJams/kJams Serial Number.xml

The easy way to get there is simply to run kJams, and go "Help->Reveal Preferences".

You can send this file to your backup computer to activate it, or transfer it to a new computer, just put it in the same place.

Your serial number may stop working if any of the following happens:

You replace or reformat your startup drive
You replace your networking card (ethernet)
Your Operating System makes a major change (eg: going from 10.4 to 10.5 can sometimes cause a deactivation)
You switch to a different computer.
your computer goes "in for repair"

If your kJams goes back to "(Tryout)" mode for any reason, simply contact me and I'll reset your activations.
