Sorry to read it doesn't work out, pimpin. Assuming your internet is up, running and fast (a simple test would be to surf around a few sites on the internet), then it is the connection to WL server.

Waiting 10 min is way too long. I have waited at most 5 secs thereabout. I will see the dot black then yellow. I used to be seeing green and yellow immediately. But recently, I almost always have to wait 1 or 2 secs. So I think if you don't get a yellow or green within 10 secs, try restarting your computer and/or your client. If it still doesn't work, try again another time (it will really spoil your game experience if this happens :<).

I am assuming it is nothing to do with your firewall settings (a simple test would be to shut down your firewall completely and see if there is WL connection) and that you did not do anything and your client somehow just stops connecting.

PS.: When you start a fresh client, you have to press a few next or proceed or start, etc buttons... I suggest you always wait a few seconds till all the images load before pressing any button. I find that this helps prevent the "black screen" (if you have encountered this) and possibly the black dot problem.
