Same here. I am having trouble getting it to run on my system, so some troubleshooting is in order. Still looking for a solid replacement for Cool Edit so I can move off Windows for good ... so far nothing is available. Ardour has a new release out too, buit as to which is better, I guess it's up to the individual producer.
I really didnt like AA, and was more of a Sony Vegas man (before it moved to video)
I first heard about Reaper from the Inside Home Recording podcast, and when it came time to upgrade, I gave it a look. The benefits FAR outweigh the low cost. I bought it in a heartbeat.
