Sorry for the hassles. The messages in the picture are of the boot process and it hasn't yet tried to load and run the Livesectional software. My guess is the SD card became damaged somehow. 

If you have a copy of the image, re-image the card and try again. You know it works since it ran for 24 hours already.

If you don't have a copy of it, then download the latest image from livesectional.com. By chance did you save a copy of the config file, airport and hmdata files? If so that would make setting it back up much quicker and easier.

Let me know what happens, I'll help anyway I can. - Mark

@markyharris Thanks Mark! I have the airports file and config file.  Not familiar with the HMdata.  I'll Flash a new card and see if it works. 

hmdata holds the heat map data, so if you are not using this feature its of no concern. Let me know how it goes. - Mark

Update- I flashed a new image on a different card, but couldn't get it to connect to wifi.  I never could get berrylan to connect to the bluetooth and I got into the config editor and put in my network info, still didn't connect.  Finally plugged an ethernet cable in and its working perfectly fine. the ethernet is working for a test but it isn't practical long term.  Am I missing anything on getting the wifi connected?  thanks!

That's a great looking map.

At this point I would just reconnect the monitor and keyboard and at the cmd line enter;

sudo raspi-config

Select 'System Options'

then Select 'Wireless LAN' and enter your wireless credentials. 

After you hit 'Finish' it will ask if you want to reboot, say yes and after it boots up your wireless should be setup properly.

Let us know. - Mark
