HTC One X - MMS Problems.... I think

[NovaRzA]

All of a sudden my HTC One X won't play/playback any MMS that I send/receive... This just happened a few days ago, I AM still able to send/receive MMS but the thing is when I go to playback/play the vids that I send/receive the screen will just turn black and it says "can't play video" after pressing play. NOW the ONLY way I can get any of the vids to play is through message options>view slideshow and its a real pain just to get to the message options. I'm fed up.... I WANT IT BACK TO ABNORMAL!!!!! lol any help would be appreciated
