Data Logging Has Halted

[yellowsnow]

My power has just been restored from another power failure. Usually after the Meteohub (NLSU2) is powered back up all works fine. Except this time.
The system will not data log and therefore no current weather data.

The meteohub log that appears to be relavent;
logger (18.08.2012 17:00:37): station 0 (Vantage), transmitter 1 active as station type (#0) "ISS".
logger (18.08.2012 17:00:49): station 0 (Vantage), data gap of 777 minutes, start reading Vantage's internal logger after 2012-08-18 04:00 (Vantage's local time).
logger (18.08.2012 17:00:59): station 0 (Vantage), data gap of 777 minutes, start reading Vantage's internal logger after 2012-08-18 04:00 (Vantage's local time).
logger (18.08.2012 17:00:59): station 0 (Vantage), wrong checksum of DMPAFT response, restarting logger read out.

The alarm log that appears to be relevant;
2012.08.18 17:02:17 meteohub: weathernet: No data upload to weather networks as sensor selected on weather network page for outdoor temp, outdoor humidity or outdoor dewpoint is not providing recent data.:

I just updated to the latest firmware to see if this would help but no change. Help!

A few additional errors/warnings;
'Weather Data Logging: running (last data: never)' - status of data logging

'No data uploaded to weather networks as sensor selected on weather network page for outdoor temp, outdoor humidity, or outdoor dewpoint is not providing recent data'

'Error connect socket 127.0.0.1:5555 connection refused'
'Warning: data logging has been halted'
