I've been using CHDK on my Canon Powershot A530 for a couple weeks now, and its been working fine. So, I decided to get another, better camera to run CHDK. So, I load CHDK on to the SDHC card, and try to manually load CHDK, but the firmware updater isn't there. I'll assume that this is one of the cameras that doesn't support it, unless somebody tells me otherwise. Then, I make the SDHC bootable, so it autoloads on startup, which is when I encounter a problem. When I turn on the camera, I am in playback mode and I see the CHDK splashscreen. However, when I try to go back to shooting mode, by pushing the playback button, the camera shuts down. Is this the result of using a CHDK beta version, or my stupidity? (Yes, the SD card is locked.)
