Ah, too bad 
I have just tested it on clean machine and working workaround is to execute this line in Terminal.app:
osascript -e "tell application \"Finder\" to «event BATFinit»"
I’m going to release a new version today. Unfortunately most beta users affected by this had to downgrade or their TotalFinder is not running anymore.
I wonder how is this possible, because standard codepath should be exactly the same as in old versions.
