I Managed to figure it out myself thanks. Having successfully installed the software, I forgot to Eject the ISO, I had used to build it. So, when it restarted, It tried to reinstall. I therefore Cancelled the re-installation, and ended up God knows where. I suspect id was in BSD. I was there that I could not log into psfSense!
Anyway, having re-read the notes I wrote myself, the first time I installed pfSense. I saw my comments, in red, about ejecting the ISO. Did that - problem solved. 😊
