What the hell is going on！？

[七草粥]

When I try to join my friend's multi-server, I get "[GameSense Client] Failed connecting to GameSense server - Error: ConnetFailure(対象のコンピューターによって拒否されたため、接続できませんでした。)
at SteelSeries.GameSense.GSClient._sendMsg(SteelSeries.GameSense.GSClient+AbstractQueueMsg msg)[0x0006d]in<a98a76624af8466183c40c347b368608>:0

"INF Discarding NetPackagePlayerStats for entity Id=171"
What should I do…；；

Steelseries gamesense is a intrusive mouse vendor app which hooks into games to "improve your experience" with things like flashy lights on your mouse or haptic feedback on your steelseries accessories. Try disabling it and see if that gets you past the error.
