I have an I 40 myselfWhen I first got it took about 450 pictures then it started acting up. So I called Moultrie and they told me to do the download over even if i had the latest version. They were helpful when i called them. Next time you call tech support ask for Ken he will help. I am not very computer literate. It was easier for me to exchange it than do the down load. Have not had an issue since. I have even bought the M 40 this year. They are both great cameras. They both have taken about 2500 pics since i got them and the battery life is great. JMO.
