update problem. (lags too)

[duybex]

i downloaded the legend III client and i cant update (i could'nt update before ether). i start the client and the update is soooo slow and eventually it gives me an error. should i open some ports? what can i do? if its a port problem can i get help fixing it because i don't know anything about port. is it firewall? if so help in that too could be great!
thanks anyways, help quick
