What i am doing wrong?
EDIT: ok, now i put in host just "us.coincatcher.net" but stays in Starting...
EDIT2: now i disable every firewall, it's ok now ;-;!
Try http://us.coincatcher.net
gui miner for scrypt likes url's to be in this format. Drop the stratum+tcp part gui miner configures this automatically. (Note in the lower left corner it says "use stratum yes") Also check your port number is set correctly. 3333 is the default port setting, most pools operate on different numbers. Other than that everything looks good.
Also ignore any comments above about gui miner being inferior. It's great for newbies and non techies alike. IMHO cgminer is much more complicated to configure correctly without a gui.
All the best,
