We had cameras and a Flir dvr installed in 2014. I installed the CMS-D3 software on the office PC and my home PC to view the camera feeds and capture video from incidents at the carwash. It worked fine until a few months ago. I can still get the feeds on my PCs in 'Live View'. Now, in 'Play Back' mode, when I display all the cameras, they all flash with the slashed red circle and if I select one and search yesterday, I get a 'Record File not found' message. The dvr has its own monitor and I can use the dvr controls to search several days of video but can't capture it. Flir support is useless. Any help would be appreciated.
