Strange question? Nahhh, but I do find it kinda strange you still want to play that game.

Anyway, might wanna be careful using pirated keys. Lots of game companies keep black lists of keys so they know who to refuse connections to if you try to connect to a company run service like Battle.net
Some even log IPs. Game companies are starting to push back concerning this, case in point Valve at the release of Half-Life2.


Probably nothing to worry about if you're just interested in single player though.
