Splitscreen Unavailable

Several days ago I was able to play split screen using two different profiles. Now I am unable to load a second profiles character at the main menu. It does not respond when I press A to join. Even if I try to have a second profile join while in game. It does allow split screen if one player is logged in as a guest however. So the problem seems to be related to recognizing a second account trying to join split screen. This is occurring on both BL2 and TPS.and happens whether online or offline. Again this wasnot a problem as of two days ago and I had not played TPS since then.
