In fatc n it isn't that tied to my computer as i change on a (very...) regular basis, let's 2 or 3 times a year...
And it has already been a bad thing for me since i've already lost my dongle one time, but that's another story.
Back on topic, have you ever asked Newtek Europe about the possibilties to get LightWave in Russia ?
I'm sure they could do something for you.
If you ever want to ask them, just drop me a PM, i know everyone in there and i'll tell them to accomodate you as well as they can.
