Please Help.  

I downloaded the wallet from the intense coin website today to my MacBook air.  I installed it and copied the address for the wallet.  I signed into stocks.exchange and went through the withdraw function to move my ITNS to my wallet.  The transaction said approved but I've not seen the coins show up in the wallet and they are no longer showing at Stocks.exchange.  The address for my wallet seemed really long but the exchange accepted the address.  The transaction is now 12 hours old.  Any help you can give will be appreciated.  

Thanks!
