I am running a laptop with Windows 8.1.  I have been using WLPG to download and save photos from a ScanDisk 128mb Compact Flash card using a card reader.  These pictures are from a special camera in an eye doctors office.  I have been able to transfer the photos from the disk to the computer since 2014.  All of a sudden the last time I have been able to do it was the end of May of 2016.  When I put the card it to read, even though the card has photos on it, WLPG keeps saying the folder is empty.  The camera only saves in .tif format.  We have tried new disks, a new reader, a different laptop, a newer camera and still have the same problem.  We need to be able to transfer these pictures off the disks for future reference but I have exhausted all my ideas.  The camera instruction manual says that the photos should open on any PC with no special programs. I am desperate.  I already have one disk that the only way I can read the photos on it is only in the camera.  The PC says the folder is corrupt.  Please help.
