Tekken 6

[srdjan1995]

didn't help. With media engine turned on the game is loading and nothing else happens (writes "now loading" in lower right corner)

Do you also see "2884"?

Delete your saved game. Don't make any new saved games.

What is 2884?

Instead of now loading, u only see 2884.. That's what he meant.. If u have that, delete save game, and don't make new one, like he said.. Than try game, without saving.

I have no saves...

You didn't created save when u first time started game? If not, then just skip save game screen and try to play game.. It works fine for me.. Alltought i don't have it anymore, but it works..
Also, were u able to reach main menu, or u have infinite loading now problem on intro video (video before u reach main menu)?
