So i have been payying monthly for well over a year so i actually own this software , I cancelled my monthly billing as i am going to buy the "lifetime updates" at the end of the month.
 
So why am in "DEMO" mode  ?
 

Never been in this situation but do you have to roll back to the version for which your license is fully paid? If your license expired over a month ago and your are using the latest update, I would think demo mode would be the expected result.
There have also been unexpected instances by other users where their sonar license has "demoized." Not seen that issue personally.

Well i am paid up to where i am regarding updates. They come out monthly so i paid for the last update,Although it could be possible but i would not be happy at all about that.
 
I guess i will contact support and wait 3 weeks for a reply by which time i will have already bought lifetime updates .
 
Thanks for the reply

Have you tried rolling back a month? Otherwise, would suggest PM'ing one of the bakers to see if they can resolve. Best of luck

Restart Sonar see if that cures it.
I own what I have (paid up front) and every so once in a while she'll go demo mode but a restart fixes it. There have been mussings on this board that it is a nagging bug they have been trying to make go away.
 

I am having this problem with Rapture Pro, and I have had an outstanding technical support case for at least three months with no progress:

It appears to be an endemic issue with recent products which is proving very difficult to solve. It has rendered my Rapture Pro unusable.

I have this problem always when internet connection fails for more than one day.
When internet connection fails Sonar needs 1 minute to start. I don't understand this.

I have never (touch wood) had this issue either in Sonar or Rapture Pro. Is it related to the monthly payments (I did an outright purchase (and more recent lifetime membership)?
Just wondering - sorry I don't have anything more constructive to add.

I have the same problem. 

I have paid yearly and now "live time".
But every time I start Sonar, it connects with the internet. But when internet connection fails, Sonar needs over 1 minute to start. And if internet connection fails more then one day I'm in demo mode. Very strange.
