one would like to help, I bought SILENT HUNTER 5 and I can not add the key, how do I get another key?
If you have a key you could try typing the key code in. Sometimes the Copy/Paste does not work. Also remember to sign in with the same User Name and Password you used when you first signed in.
If you still can't get it going you may contact Ubi Tech help and see if they can help you.
