QB (and these other high-rent programs) has an authorization process (checks entitlement) at startup. Your license check failed. These newer programs use databases and relational files (well, QB changed around 2006). That's why cloning doesn't always work. The same issue comes up when using Carbonite (a mirror process) as a backup vs making client backups using the program's backup function. Even Dropbox (mirror) vs Box (managed access) reveals these issues; you get "conflicted copy" with Dropbox.
