Pretty much it. I create a profile, click done, do all of my settings, then come back to the profile menu and its gone. Sometimes it will save, but as soon as I exit MXB and re open it, the profile is gone again.
I don't know whether it's related, but sometimes the game loses or messes up my controller calibration.. It still works, but it's whacky, like it becomes super sensitive. I go to calibrate and the markers are already to the extremes and slightly moving before I've touched a stick..
