Do I still have to pay an outstanding

Based on the facts you presented, it's most probable that the statute of limitation has run out and you now do not have to pay a penny. However, to answer your question I need some additional information from you.  For example, when was the last time you made payments on that credit card? Has the creditor made any attempts to sue you? Have you recently had any conversations with your creditor or debt collector in which you reaffirmed your debt?
