Any online characters will not work if you have an outdated game, there may be a work around but for now you must buy the game in order to use the online characters..

If you're having trouble using the storymode characters, go into their folders and rename the folder from update_4 to update and it should fix the problem, make sure to do all of the other steps shown on the webpage.

Everything marked with ONLINE you will need a legit copy of the game for.
