I tried refreshing wof page few times but id does not work. I have the same error message about expired spins so I guess I have same problem like you did. I'll still try a few things but if you remember which method you used I would be grateful if you could share the procedure.
I've mentioned the method that "was" working before here :
https://bitcointalk.org/index.php?topic=320959.msg65383018#msg65383018Basically we were able to bypass the invalid spin by clicking play one, and then simply play all
But now, if you click play one, total spins amount becomes 0
So the only solution now remains in the developers' hands
I think the bugged wof is the one that was for clicking notifications. Some months ago they added a wof prize for opening the site through notification once per day. Then they paused the prize, after that we got one single bugged wof in our bag of wofs.
I think if they resume the notification wof the issue will be gone.
