Hi crashz,
A shut down on a blue led might indicate a full memory.
If it's a firmware issue you can download the 15-10-08 Magic.bin update here somewhere and install it to your pencam by having access to the three drives. Holding the button while inserting in usb and release button (after 2 seconds on older model, after 10 seconds on recent ones).
Only if you have the older model:
Before upgrade: Ugly green time stamp, good video quality at 15 frames per second and 1% audio lag.
After upgrade: Clean white time stamp, better video quality at 12 FPS and .375% audio lag... your choice.
Peace
Gibsy
