Hi Ed,
I just PM'ed you. Please contact me and we'll try and do some diagnostics. Once you have successfully authorized SONAR either by connecting to the internet from your main system OR by following the offline auth process, there is no further need to be online. Its a one time process if you have purchased an annual membership.
If that is not the case then something is not working properly or your membership information is incorrect.
Please contact me and we can figure it out.
