Replying to Movie Recording Has Stopped Automatically

can anyone help me with this? I have a refurbished canon t2i and am using a sandisk class 10, 8 gb card for it. Now whenever I try to take video, no matter what quality or fps, it will give me about 5 seconds of recording, then the message "movie recording has stopped automatically". Anyone else have this problem and know how to fix it? All the discussion I've seen when I searched seemed to be related to shitty cards, or cards with classes lower than 6.

anyone?
