Please help >.<

i dont know wats wrong... b:cry i have downlaoded the new patches and it still tells me that i cannot connect to the server wen i try to log. The notice thingy also says page cannot be displayed or sumthing. I completely removed my anti-virus and double checked the firewall is off. I Dont understand y its not working. I dont think it has anyhtign to do with the firewall since it was workin prior the 37 and 40 update!
I also tried opening PW off a friends laptop through a wireless network and it works fine so the files are all in order. If some could please help it would be appreciated
