What patches do i need for BF2?

i just installed bf2, a coppy a freind gave me
i just wanna know what patches i need to get so i can pay online

thanx...... some links would be helpful also

You need a CD Key. I think you can still play ofline without a CD Key but until then.. :/

Well if you manage to find a cd key on a site it only works when nobody else is using it.

Yeah you won't be able to log in if someone else is using it. If you're friend ever gets bored of BF2 you could always ask him for a loan of his account while he isnt using it. (just don't do anything silly with it :P).

Oh and I don't think you need patches if you're friend bought the game recently, if you want to check google it!

this is illegal!
