Game Camera help needed

As I posted in a prior thread, I bought a Windgame Innovations Game camera at Bass Pro a little while back. Model z4, 4 megapixel. It seemed to work fine for the first couple of weeks I was getting between 6 and 10 pictures in a 24 hour period. Then, a week or so ago I pulled the SD card and it had nothing on it. I know that something had been there on account of all them golden nuggets were gone. Thinking that the batterys had gone south, I got fresh ones , rechecked the settings for time / date etc., and again nothing.
I took it down and brought it to the house and checked everything again and it looked fine. It will take a picture, proving that the SD card is still good, but I have to be within 5 feet of it and move around slowly. Even at that it is hit and miss.
As usual, I didn't read through the included paperwork thoroughly and missed the part that said I had 14 days to fill out the warranty information or else there would be no warranty. Not much info on the net about problems with this brand so I was hoping some of you guys may have some experience with the WGI brand game cam and could offer some advice.

I bought a wildgame innovations red6 (I think) back in Sept. it wouldn't take pictures during the night. So, I called Wildgame Innovations and they told me I could send it back to them and they would send me a new one. The turn around would be 3-4 weeks, or I could just take it back to the store I bought it from and exchange it.

So, my opinion would be to call Wildgame Innovations, I think they'll help you out
