If i download guild wars on one comp. and use the access code can i still use it on other computers to ?

Answer 1

You can install on as many computers as you want. Don't enter the access key again on the 2nd computer, just sign into the account you just created on the first one. Only 1 computer can use it at a time though because you only own 1 account.

Also, never buy a used account. Accounts are not transferable. Anyone trying to sell you a used one is most likely just trying to scam you.

Answer 2

Yes, you can use your account on any computer, just only 1 account can be logged in at a time. So I couldn't have 2 computers and 1 account and expect me and my friend to play.
