Hey guys the last few years we've been having trouble with trail cameras. We run wildgame nation cameras and use laptops or a wildgame nation card reader. The cards we use are cabelas brand. Some cameras are at most 3 years old and all the cards are less than a year old. Many times when checking the cards we will get 1 of 2 messages. "No file" or "there is a problem with this card" we never had these problems or any problems for years. If anyone has any suggestions or thoughts I'd love to hear them. Thanks.
