Oops, I nearly forgot to update this page (once again), I've released an update for Chat Logger++.
This version should be a bit more resistant to Steam updates than the previous one.
The tray icon now reflects the state of the logger (connected / disconnected / a feature is broken).
And finally I've added a single instance checker, since it makes no sense to have multiple running at the same time.
You can download it from here
