Hello, I downloaded and gave a try to ML for the first time today and everything was fine, then this blue screen started to pop up on my second SD card:

I just had this Canon repaired

. My heart pumped quite a bit, but I was able to get back in the camera simply by removing the batteries but I had this Blue Screen now and then, was almost impossible to do anything the first minute. I fortunately had time to uninstall the firmware, and my camera seems to run fine but it scary hot. Did few video tests and pictures, all seems fine but I fear something may be damaged.
Anyone had trouble with this and can help out?
Thanks
