Hello guys. Would be nice if you could help me a bit.So i just found some old cdkeys from reign of chaos and frozen throne, i installed them but when i try enter to battle net it says `Unable to connect to battle net. You may be trying to connectto an invalid server. If you are using modem ,you may need manually connect to battle net.´ My question is , can i still enter battle from frozen throne? If yes why it doesnt let me , and if not i read some comments saying that having the old cdkeys you can have reforged for free. I am really confused. Thank you very much and sorry for my English.
