Sonar and this forum are heaven compared to the world of Roland-Digi-Avid-Pro Tools, or whatever name you want to use. I had an issue with PT (Sooner or later I always did...everyone does.) and could not contact anyone, so I went to Guitar Center in Nashville, where I bought it. The manager said he couldn't even get in touch with them. You would think the manager in Nashville would have a hotline to Pro Tools as much business as PT does in that town.
I don't know why you're mad at Cakewalk when the issue seems to be with Steam. Are you leaving Steam too because of lack of support? Doesn't sound like they've fixed it either.
With all due respect, I don't think you've dealt with the arrogant hell-hole world of Pro Tools. For one thing, it costs more and does less than Platinum, and you're gonna love that iLok. I had so many issues with PT that I finally gave up and came back to SONAR full time and love it. Unless a lot has changed recently, PT support is TRULY a nightmare and the forums are rude, arrogant, and basically obnoxious to deal with.
I had another round of trouble with PT this summer. I went to their forum to ask a simple question and the reaction and replies were beyond rude. After that experience (and other countless times over the years), I came over here and asked a few simple questions about Sonar. The people here were polite and they answered my questions and helped every way they could. This is the best forum of the DAW world. The hospitality and knowledge base here, plus the upgrade to Platinum with lifetime upgrades, sealed the deal for me. My DAW life simplified and I started enjoying it again. I'm not messing that up with another excursion into the land of PT or Apple.
As an experiment, go ahead and leave Sonar over a problem that Steam should deal with. Jump in with both feet with ProTools, and make sure you have $700 and six months of time you don't need because if you can't solve a problem with Steam, you are going to be swamped in PT. Try it, but you will be back to Sonar. And when you return you will have a greater appreciation for Sonar and this forum.
I'm not trying to be harsh. I just want you to know that the world of Pro Tools is far from perfect and it's not a quick fix, or a dream come true. Proceed with caution.
