Hi, I don't know if this qualifies as a bug per se, but I've been using Byte Tuner to flash my car many times and now all of the sudden it gives this error. I'm on Windows 10, MS45.1 It will read codes and clear them, but will not datalog or flash anymore. I did install some datalogging software on this laptop for another application but idk how to see if that is causing a conflict or not. I have closed all applications and restarted the laptop several times.

When you try to connect the OBD module flashes green LED several times so it's definitely trying to do something. Verified switch is in far right position.

Probably simple but idk what. Help?
