Have you updated the correct driver for qcma. That one seems to be an issue every now and again. There's a youtube video about a driver called zandig, I think. Without that qcma doesn't seem to be recognized. Other than that. Try reinstalling, after you made backups of the folders that you have your save data and dlc etc. If that doesn't work, then, I'm not sure. May someone who has more knowledge in this issue can assist.
