I was also getting a little worried but then I read back in the thread and noticed that the team has been on holiday over the xmas period and they went through a server change at the changing of the year. I was patient after my cashout and it arrived the next day, it is entirely possible that larger transactions will take longer due to the time required by the BTC network to process them, so my advice would be to do multiple small cashouts, so one every day, instead of doing big chunks. 

Good luck out there
