XCN does not have any pair on AEX anymore, but it seems you still can withdraw your XCN. I have to sync my Cryptonite Client before i can withdraw from AEX, but right now i have the problem, that my cryptonite clients hangs at start and says something like "searching again -2147483648%"

edit: messed up my installation, cleaned up and client is working
i started a withdraw, they stated that the withdraw have to manually approved within their working hours...
