Hi,
I tried installing 5.4.001 last night -downloaded and flashed via 5.3.039 Image Manager, restored settings and plugins but ended up with a crash-reboot sequence. Lousy shot of the error message attached.

To recover, I performed my first USB flash (look for the press power-button message on the front panel, not the TV screen, doh!) so I don't have logs for 5.4.001.
Hope this is of use. I probably wont be allowed to break the machine until seriously off-peak hours but let me know if I might be able to help debug.
Cheers,
Martin
