I just entered 50-some odd of my unused quest cards and I kept getting the VMK does not recognize the code thing. Please help!

Try entering them in again and take time between entering them ( if that makes sense) lol if not send the code to Contact Us and they can help

sometimes just signing out and back in will fix that.

Check the expiration date on the back of the card... yes they have expiration dates. They will need these codes again some day:)

Sorry I was at my grandma's house , but I checked the expiration dates and they're all good so I will try my codes again once VMK opens Thank You.:)

Another thing....yesterday a friend told me her codes would not work in her room only in a public space. You may want to try that. Also, after putting in so many codes you have to move rooms or they dont work. If they still dont work after changing room, log out and back in. When I come back from WDW I usually have about 150 codes to put in and have found these tricks very useful when putting them in. If you still have questioins feel free to ask me, but you may want to PM me with the question because I wont check the thread. :)
