How do I buy a full copy ?

I have been using the Demo copy and it works like a charm but I can't find any one around here that carries it so that I can buy the dam thing.
I am in Edmonton, Alberta can any one help me ?

Re: How do I buy a full copy ?

I know very little about computers but I have also searched for the program myself. You can buy the program from their website, but I do not know how reliable it is. The cost is approximately $149 U.S. at the following website: http://www.i3net.it/Products/dspQuattro/Asp/Index_EN.asp?Language=EN

Re: How do I buy a full copy ?

Yes, you can buy it from their site as a direct download and they will give you a machine-specific authorization key-- if you end up switching or upgrading computers they'll let you have a new key, and you also get free upgrades. I've been using the program since it first came out, and I'm very happy with it...
