Hey guys, everygame I buy, and there is free DLC, it never works. I recently bought Batman, the best game ever sums it up, and there is the free Joker challenge. I went to the store and dl'd it and then installed it . 
I put the CD in and then played, but no Joker challenge? 
Is it because I dl'd it while the CD wasn't in the ps3 or is it something else? Maybe im looking in the wrong place? Someone who has the game, please help.  
thanks

It should work providing that the region you downloaded it from matches the region on the disc.
 If you download Batman DLC from American store and use an american disc then it should work.
Any chance you are mixing up regions?

I had to download it 2 times to work!

I have a US account and I bought the game on holiday :S, any way to switch regions? 

Sadly no, DLC is region locked. You can make another account that would match the region from where you bought your game.

Are you actually going to the downloaded file in the XMB and installing it properly...  I know its a slightly insulting question but these things happen.
