New to Whdload what's The crack?

[carvedeye]

Before the game loads a screen pops up saying unregistered then some load and play fine others all that happens is I get a demo of the intro but nothing else and some won't load at all it just says that it needs to be registered.

The demo at the beginning is normaly of the cracked games like skidrow etc...if you left click the mouse it usually gets the game going.
