Hi the same has just happened to me, im doing a pregnancy diary and filmed my hubby and dad building the nursery furniture only last week, today when i went to add some more of my thoughts to the tape all i got was EO3 flashing up and was unable to open the tape thingy to see what had happened. camera been kept in a protective bag and in the usual way (away from heat, sunlight damp etc) did you ever get a solution?
