Kar,
95+% of the functionality in IO is FREE ...
Once you've played with all the FREE parts you can get a 30+
day FREE trial to test out all other features ...
As far as one time fees are concerned they never existed ...
As far as your idea about a lifetime fee is concerned, feel
free to contact me directly via email about this if you are really interested as
this is an AmiBroker forum not an IO forum.
