BF4 DLC Crashes

So I used to play BF4 on my PS3, then upgraded to a PS4. I purchased BF4 Premium edition for the PS4, and downloaded and installed the game. Overnight, I downloaded the DLCs, and planned to play them today. However, when playing on a map that belonged to the Final Stand DLC, like Hammerhead, I was stuck with the infinite loading screen. When playing on Operation Metro 2014, which belongs to the Second Assault DLC, the game crashes with the corrupt file error. And the last map I tested was Dragon Pass, a map that belonged to the China Rising DLC, where not only did I have the infinite loading screen, but one of the pictures the game regularly cycles through is glitched and messed up. However, I was still able to play on the standard BF4 maps. Does this mean my DLCs are corrupted? I remember accidentally TURNING OFF my PS4 mid-download, only to turn it back on and resume the downloads. Could this be a cause of the problem? I'm assuming the best way at this is to delete the entire game (cause you can't delete DLCs alone) and reinstall it, along with the DLCs. Any ideas? Thanks.
