I already purchased particleIllusion 3.0. but I did not yet activated because in activation page it says, the activation code works only for one computer. I have two computers one @ working place and one @ home.so what can I do .
You can only install and activate on miltiple computers if 1) you personally own all of the computers 2) you are the only person running particleIllusion on them.
So you *cannot* activate on your work computer and your home computer, unless you own your work computer yourself. Otherwise, your employer (the one who owns the work computer) needs to purchase a license too.
