I don't think there was a problem with the withdrawal system. When you played the network took about 1h for a block and subsequently 22m. And you played for a very long time, if you tried to withdraw within the 1h window you should've been able to withdraw around 9:40pm EST, but you played until 10:20pm EST.

You deposited 37 BTC in block 272219:

* 7 BTC in tx 73a7bc482945c4c4893f500afa7f5fbf00eacc0ddaf829c3b9f818699fb4c06d and
* 30 BTC in tx 5bee19420709eef02ea43e427756eea732df37b83aab5ef87aa3c90b3a6ceb77

According to blockchain.info, they saw the blocks at these times:

#272219 2013-11-30 02:51:50
#272220 2013-11-30 02:52:31
#272221 2013-11-30 03:54:04
#272222 2013-11-30 04:07:45
#272223 2013-11-30 04:19:14

You tried to withdraw 3 times, at these times:

* 2013-11-30 02:59:49 requiring 4 confirmations to withdraw 46.45761505 BTC
* 2013-11-30 03:08:42 requiring 4 confirmations to withdraw 46.45761505 BTC
* 2013-11-30 03:14:11 requiring 4 confirmations to withdraw 59.65071166 BTC

All three attempts were during an hour-long gap between blocks #272220 and #272221, which meant your deposit had only 1 confirmation.

Your last few bets were timestamped like this:
