Does anybody know why a SD Card would not be recognize by the Whistler program but would be recognize by Windows 10? I am trying to use a 16GB SD card so it could be formatted but I want to use on the new WS1088 I received the other day, but the Whistler program does not see it, but Windows 10 sees it. I record a lot of conversation but I hate to use the 4gb card they supply. Any help or suggestions would be appreciated.
