I have SPLAT installed on three machines. Two are laptops that are rarely connected online, one which I try to use in live performance, the other I use to record live with friends way off the grid. None of these are ever used concurrently. (No reason)
With recent updates on a trip recently I updated both laptops so I could use them as intended, updated through command center. I continue to open one or the other and find SPLAT in 'Demo' mode. This requires the pains of finding a wifi spot, open command center online launching from there and the Demo mode goes away . But it always comes back. Is there a way to prevent this? Becoming not worth the inconvience to use at all.

I'm having a similar problem that I posted about recently...

Unfortunately, I have gotten no replies, and also no feedback from my tech support inquiry. So I'm still in workaround mode of having to open Sonar from Command Center.
 
For ease of finding it, here is the text of the problem:
 
Re-opening an old thread...
 
As of last weekend, my SONAR Platinum installation also will only open in demo mode. If I open SONAR from within Command Center, then it opens normally, and I can save, etc.
 
I don't use SONAR regularly, so unfortunately, I can't pinpoint what might have changed to trigger this. I do keep up with the regular SONAR updates, and download them via Command Center, usually within a couple of weeks of their release.
 
From reading this thread, it sounds like the issue is on the Cakewalk server side. I did try to use offline activation, which appeared to be successful, but which did not resolve the problem. I'm open to any other ideas.
 
I did submit a case via SONAR Product Support, but they have not responded to my original request, nor to my follow-up request...

Okey dokey, I appreciate the heads up, I won't get my hopes up!
Thank again!

Hi. For the pc that is seldom online, you could do an offline activation.

All the best.

We had made some fixes in 07 to address this.  Please use the Early Access build, or wait for the official one soon.
Sorry for the trouble.  Having a legit copy demo mode is certainly not acceptable.

Thank, I will wait and continue to launch through Command center.
Grandpa said patience was a virtue...

The 07 release is out. Go get it.

07 release did not fix the problem for me. Still end up in demo mode if I launch from the desktop. If I launch from within CC, all ok...
 
 

you may be running on a Windows user account that has restricted permissions. This might be a non-administrator account with restrictions on writing/copying files in certain directories. If this is the case, you might want to up the privileges of the account or run as an administrator. 
 
Any aggressive firewall/anti-virus settings could also contribute to the issue. Try temporarily disabling any fireware or anti-virus software to see if Sonar will authorize. 

For better or for worse, I haven't upgraded my installation of Sonar Platinum in months, for fear that this issue would befall me as well. At present, I am able to successfully use Sonar Platinum on a PC that is not connected to the internet, without Sonar reverting to demo mode.
 
My concern is based in my experience with Rapture Pro. I am not sure of this timetable because I did not anticipate problems and therefore did not make notes, but it appears that my version of Rapture Pro worked fine for a brief period after purchase until an upgrade, after which it always reverts to demo mode hours after re-authorization. My problem may ironically coincide (and I'm not sure) with the upgrade that introduced offline authorization.
 
As a result, it is my suspicion that there is an endemic issue with Cakewalk products that use the current method for authorization. I'm sure that Cakewalk will get it worked out, but it has been a frustrating issue for me for almost half of a year.
