I downloaded the launcher using the link from my original purchase email, but now the launcher doesn't open at all - I click it and nothing happens. I reinstalled the launcher twice to be sure, but I'm still unable to open it. Here's the contents of the log file, but note that this log file was last modified today when I opened the old launcher - it does not appear to have been modified when I attempted to open the updated launcher.
Spine Launcher 1.8.06-full
Mac OS X x86_64 10.9.2

Spine launcher update required, please reinstall.
