Oh, It's ok Buddy!
Well if you don't have such information like CD - Key and The Secret Question Answer, I suggest you be very careful due to the fact that the real owner will be able to re-call the account at any point and you won't be able to get it back.
Few things you can do actually. Try Selling it to who ever. There are many guide on how to do it and you might say, " Well I don't have full info!" Well simply just tell the buyer that You will not give full information until you get your money onto your bank account *LIE* and it takes 3 days for paypal to send over to your bank account.
Paypal How ever works in a very funny way and I just found out recently that Using Australian paypal does not require you to have any card or bank accounts for the paypal to be verified. CRAZY, I know. ( I tihnk you just need to call them ) And don't use the Personal Account use the Other one.
Also Markee dragon is where the magic of scamming happens this days so start there :P
Best of luck!
