You need to hit 100 coins on the pool before they are transferred to you. If hit ctrl+F and enter the last digits of your address, you can search the page for your miner stats at the pool page
You are showing a pending balance of 48.4 coins.
Also, when you join a pool, it takes some time for your historical shares to fill up, so you don’t make as much right when you join a pool, you need to hang around for awhile to get full shares. I think the 50-50 pool is 500 blocks for this to happen. 4 minutes per block by 500 blocks is around 5 days.
