Write to support@sebb.games. One person reads it, and that person also writes the game, so a clear report gets fixed faster than a long one.
Loop Rally needs OpenGL 3.3. Update your GPU driver from the vendor's site, not Windows Update. On a laptop with two GPUs, make sure the game runs on the dedicated one.
Plug the wheel in before starting the game, and check that its own driver software sees it. Then open Options → Controls and pick the device there.
Purchases go through Steam, and so do refunds: use the Steam refund request, we cannot issue one directly.
