RSPB Nature Camera

I have a couple of problems with my RSPB Wildlife Camera. ! - the mounting bracket has broken off and cannot be reattached. 2 - I had not used it for some months but when I did this week it would only record one video despite having a six-hour work period set up, and yes I have checked the settings! They are the same as previously. The old batteries were completely empty, and I use rechargeable ones. In fact, six of the eight that had been left in the camera were unrechargeable and I had to buy new ones. Anyone help, please?
