im too broke to buy the game new, so im buying it second hand, now the guy that is selling it to me (found on kijiji) is providing the original CD-Key, will i be able to go online with it, or no because he registered with it.
Typically, like with UT3, it just un-registers the game copy at a different IP so you can type in the key again and use it at a different locations. Happens alot when I move my computer between my houses. GTAIV may not work the same way. Ask R*
