I've had a few weird things happen with most recent installs, Bruno helped me through a major issue in email today (thanks again).
I'm trying to complete the updates, and received this whilst trying to install FNC Blox:
WARNING: Older TMS FNC Core (18.104.22.168) installation found, please update the TMS FNC Core to version 22.214.171.124 first. Please also download & install the latest version of the following products: TMS FNC Chart TMS FNC UI Pack
I've uninstalled everything and reinstalled (leaving Blox as last lib to install).
It just repeatedly fails with that same message.
