Serious question: Would it be foolish to still buy Sonar Professional if I can get a couple of productive years out of it?
It's the only interface I ever liked and I'm am finally going to buy it legitimately.
If I have a questionable version of a different product (like Sonar Producer 7), should I just use that until something hopefully moves positively forward with this interface?
Any feedback would be appreciated; i'm sure others would like to know

You can't purchase anything here. Kinda wierd to claim usage of cracked software on the manufacturer's forum even if it's not being supported.

The interwebz, where everythings free until you wanna go legit and it's too late.

No missed the chance to own it.
There is really no reason not to own a DAW, Reaper is like $60 and very good but it takes alot to be able to make it easy where DAWs like Sonar have made it easier from the get go.
Right now for $149 till the 20th you can get Samplitude Pro3X Suite, much too good to pass up but you will have to get it NOW, today!
There are plenty of cross grade deals but the ProX Suite is the best value; comes with SoundForge and 70gigs of SoftSynths and sample libraries.

You will perhaps forgive me if I sound too judgmental, but I consider cracked versions of software to be one of the major reasons we lost our beloved Sonar.
 
Do whatever you want, I couldn't care less. I do hope that a virus from one of your questionable versions of software brings down your system to perhaps emphasize to you the immorality of your ways, but I seriously doubt even that will make the point to you.
 
Let me put it another way to you: I've been carrying you for many years. I've always paid for all my software. I (and the other individuals here with ethics) have been those who have unknowingly and unwillingly given you license to steal applications from those who are underpaid to develop them by supporting the software in the way required by law. If I or anyone here helps you in your issue, we take part in your thoughtlessly willing and destructive behavior. 
 
Believe me, I do not have any illusion that what I or anyone say here will have any effect on you, but know this: there will eventually be payment exacted from you. I hope that this will happen sooner rather than later.
 
Posting on the website of defunct software you of which you use a cracked version? Your personal ethics are lower than pond scum.

IMNTSHO, you should have bought it back then. Loathing and judgment aside, you can probably still buy it at Guitar Center or online somewhere. I think it would still be worth it. I can commend you for finally wanting to go legal.
 
Just curious, how would you feel if whatever music you make, was getting pirated and it became something like Gangnam Style? And, you never saw a cent? All kinds of people making money from your creation as you sit at home broke...

I’m curiious.

Do you pay for the music you listen to or do you steal from musicans and songwriters as well as software companies and their employees?

Kind of late to do that. No one can change the past, but you can control present. Research DAWs and actually buy one. Piracy didn't kill sonar, but certainly didn't help. You can't help sonat, but yiu can help your conscious and other companies struggling.

Sonar is now dead, so why on earth would you buy it?
Take your money elsewhere.
Try the other DAW's by downloading their trial versions.
Then buy the one you like.

Haha... I think it would be foolish beyond measure at this stage. Copped a bit of a beating from some seriously judgemental high horsed keyboard warriors there e3do! You would think you just confessed to shooting their mothers:). Glad to here you want to go legit. Always a better way if you can scrounge up the cash. I suggest you have a look at Studio One 3. Happy musicing!

If the authorization thing was squared away, I would probably say yes (at a reduced price). Because it is still a great software.
But not knowing if Sonar will hand over this authorization code or not, I wouldn't buy it.
