I don't think re-installing the game would help... because it's a connection problem. But does it work in Lonely Cave, or do you still get bad tokens? It might just be a connection problem, but maybe it only effects a couple people? I don't know, maybe wait? But as you said you tried for hours. But I guess if your connection is fine and it's happening to all of your maps, maybe you can give re-installing a shot. If that doesn't work that personal message some one you know who can probably help... a staff member, maybe? I hope you figure this out.
Feral Heart is having some connection issues lately, too, it mght just have a bigger effect on other people. Not sure, though. I hope you get this fixed. c:
And then Suragaha posts the minute before I post this... xD
