What a blow.
Only now when looking when I did purchase (Oct 2011) I saw the download link that I got sent.
While it is all very logical once you know, for the unsuspecting user it is a pain in the .... neck. The word (DEMO) in the title bar is a bit too little to make it obvious that you are handling a demo version (again, once you know it is obvious).
How's about a big fat DEMO note in the splash screen when starting?
