Hello: I've been running CHDK perfectly (and gladly) for some time now, but recently I'm having this problem:
When poweing on the camera, chdk will display the stored photos shortly and shut down the moment right after. It won't last five seconds from pushing the on button, it just powers off automatically. I can only turn on the camera after many tries. Half pressing the shutter button sometimes helps, as well as keeping the power button pressed, but even that sometimes fails.
Removing the memory card and write protecting it (thus disabling CHDK) makes the camera behave normally.
Any help?
