legally?, hmm yes and no, strictly speaking licences have expired, and i dont think you should under be using it really, however just to be on the safe side when i used it, i e-mailed pixel farm, they really didn't care about me using it, and offered me a ?50 student licence of the full pftrack.
i thought 2.11 was the last version actually maybe i imagined it... unfortunitly my pc is dead and buried, i'm yet to recover stuff from the drives, so i cant get it.
if you are thinking of using icarus for comercial reasons i think its a bit dodgy, and a much better alternative is pfhoe! PFtracks little offspring
