EmonPI failure after power outage

Had a power failure at our house while on holidays. Unfortunately, it seems to have corrupted my emonPI as it will no longer go any further than displaying “Booting” on the LCD screen. Can’t connect to it via Putty either, so I’m assuming there’s nothing to be done to save it other than re-flashing the SD card and reinstalling.

Now, what is the best way to restore my data? Can I pull it in from emoncms.org where I had an account? Or should I see if the local database on the card is still okay and make a copy of that before reformatting the card?
