How do I insert a picture? Having difficulties I tried clearing my flash player's cache except that it won't work... ;(

What should I do? Everytime I try to access my account, just before the thing fully loads, it says this: Cannot establish connection (host: 37.48.74.165, ports: 4444,5190,5223,5222,5050). I am using the house WIFI and it has a strong signal. I even resetted my Safari to try to solve the problem... HELP! ;(
