i have one of the moultrie i40 cameras and i did a test, it said the same thing error 20000. i called moultrie the other day and they told me error 20000 means that my flash is not working, which is not true because i get excellent night pictures. so im gonna run it till it dies if that happens. moultrie is going to put all the codes on there website and what they mean. they are going to send me a copy by mail too.
