"SONAR will go into Demo Mode in ____ day(s). Renew your membership or buy SONAR before time runs out."

Can anyone answer why this message pops up whenever I open Sonar? I've seen money leaving my account every month for a full year and was under the DISTINCT impression that after a year, whether I opted to continue paying or not, I actually OWNED the version of Sonar I last downloaded. Manchester, I believe it's called, as of this post.

But am I mistaken? In 11 days will I be reverting to Demo Mode as the red warning box tells me?

This will probably require Cakewalk support.
Do you use the Command Center to install SONAR?

Thanks you scook for your reply. 
Like Hanemkat, I am also understanding that we can use our latest version of CW software if we do not renew the "subscription".  Is this correct or not?

There is no requirement to renew. It does not matter which payment plan was previously selected. A perpetual license is immediately granted to those who purchase SONAR with a single payment. Those making monthly payments are issued a perpetual license after completing 12 consecutive monthly payments.

Perhaps this has do do with the Update 1 for Manchester or something like it:

That was in part why I asked the question in msg #2. Waiting for the OP to respond.

I'm having a similar problem.  I did DL the latest version of C3 and installed Manchester just tonight so I should have the latest patch, (I'll need to check the release number though).  I'm getting the "running in Demo Mode" message.  I was able to roll back to Lexington.
 
Thanks.
