I'm using a PCI-1405 with a JAI-MV50IR camera. I've been using it for a few months with no problems. Today, when I try to grab or snap images using MAX it tells me that it cannot find a recognizable video source. Everything is plugged in and connected. Nothing has changed since I used it two days ago. I can't find any settings to toggle or anything. Why can't it recognize the same camera it has been recognizing for a long time?
