I'm assuming that this issue is occuring for you on PC.
If that is the case, Manually delete all content in your DLC folder (C:\Program Files (x86)\Origin Games\Mass Effect 3\BIOGame\DLC)
Open Origin and redownload any DLC you had
Then restart the game
If you're on XBox, clear Cache then restart game.
