WWE 12 glitch

So yeah, I was playing WWE 12 and had downloaded some DLCs (the entire Divas and first package, as well as Fan Axxess) and after I began to play again, the game began to lock up after the first match in Exhibition. After browsing the WWW, I found no way real way to fix it on my PS3 but did see some people suffering the same problems (wether it was for the same reason, I'm not sure.) so I deleated my WWE 12 data and, somehow, that fixed the glitch... Don't know if it works for everyone, but it was worth trying.
