Jag läste på steams hemsida om problemen med cd keys osv att man inte kan använda sin vanliga cd key nu efter att cz kommit men det är inte riktigt sant.. det är tyvärr bara rykte. Och så här står det på steam hemsida om cd keys..


When you sign up for Steam, you create a Steam account, which contains all of your Steam games. You can use your Steam account on any computer, so that you can play your games no matter whether you're at home, at work, or on a friend's computer. If you buy a new computer or need to re-format your old computer, you can keep using your old account-Steam will automatically download all of your information to the new computer. Although you can use your account at any computer, it can only be used at one computer at a time.

CD keys are special serial numbers printed on retail copies of Half-Life and other games in the Half-Life family. Before Steam, this key was used as an anti-piracy measure, and became the user's unique ID code when playing the game online. With Steam, the CD key can be used as a "Proof of Purchase" code that will grant your Steam account access to some of the available games through Steam.

Each CD key may only be used with one Steam account. Once used, it is permanently bound to that account, and may not be used with another. Deleting the account will not free the CD key to be used again. One Steam account, however, may have more than one CD key registered to it. For instance, if you have an account with a Counter-Strike CD key registered to it, and you purchase HL2 in the store, you may use the HL2 key on your Steam account to grant access to HL2.
