Zones stopped working, program crashed and even with save lost data

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I have no idea what steps will produce the problem, but will describe best 
as I can what happened.
2. Playing cartridge on  (Android capable) Garmin Monterra.
3. (MORE than one error, but first one is described) Reached a zone and 
received hit a bug Java runtime exception tried to call nil stack trace: at 
@E:/webtempfiles/6c819be4-a3bc-4ddc-a56f-dd6c8048cad9/EMH-new. enc:1649
4. Rebooted app and it SEEMED fine, but NO longer gave game pieces, only thing 
is being unfamiliar, didn't realize I wasn't receiving things I should until, I 
received another fail. (including SCREENSHOTS of all errors)  With this fail I 
again rebooted the app.  Still didn't seem to be working so I reboted my entire 
device and received a NEW Error when I tried to reload the saved game: Could 
not load cartridge probleme loading game: null 

What is the expected output? I should have been seeing map pieces or words 
detailing what happens next. 

What do you see instead?  Instead just kept receiving errors, even when 
restarting app and rebooting device


Please use labels and text to provide additional information.
I have screen shots to be included.
5 images attached. 1st 3 are errors received when trying to play the cartridge, 
the next one is showing what things were saved before rebooting device and the 
final image is what happened after rebooting the device.
