Hi Tom,
Unfortunately that blue screen you are seeing with the Keil Dev Tools indicates that the device has lost it’s web files.
Please raise a ticket through the link below and our Tech Support will talk you through the steps of getting the device sent back to us;

Sadly we do not have a fix for this that can be implemented in the field yet, it has to be done by us here at base.
Thank you in advance,
Josh
