When I chose Help/Check for Web Updates, I get this:
You indicated that you are currently using: NoteWorthy Composer Version 1.75c (win32)
*** You are using the latest release of this product ****
That is not true, apparently.
Hope that helps.
Perhaps a bit misleading - but you are using the latest version for the first release of NoteWorthy, version 1 - there is now, however a version 2 for which you may have tp pay to upgrade. I believe the message you received primarily is related to free upgrades for the version you purchased.
Have a look at this link. It should tell you all you need to know

Thanks for the nudge. We generally consider the NWC Version 1.* version as its own product. We will add some language to reference NWC2, though.
