Hello!
I have a problem. Some mods which requires DLC such as: Dawnguard. I installed the (.BSA, .ESP) mod after the game not load or the DLC disappear.
What can I do? Do you have any idea?
Please help me, many thanks.

Mods on console? No dice, sorry.

You can't legally use mods on the PS3 (Or the Xbox) so you won't be able to get any help in that regard if you're trying to put player made mods on the consoles.
