Game not connecting

Hey. I recently got a little lcd display to put telemetry on when im playing games. i set it up today, and it worked fine for an hour or so. after coming back, it now just isnt working no matter what i do. I go to launch the game (f12021), and the dash i am using. The dash displays the time and its default screen (no telemetry), and simhub says the game is disconnected and waiting for data. i have tried a reinstall, and fiddling around with WMI. I dont know what to do, help please!
