Well there is still some hope left. I just logged in again and checked the cashier. This time it loaded right away. I checked my account history and it said that the overnight express request for $50 was approved on January 9th. So maybe within a week or so I might get the check in the mail. I'll keep you posted.
When did you win and cashout? How come you have not complained about this? I think if you have not received your cashout, this should be looked at more seriously, many scamming sites...
