my dear brother i'm sorry that u had to reformat ur system again and again. many people get this error so they say it is fake one and many say include me that its working fine, u can see in the threads, as i think this is an ip problem from some places that itune recognises ur ip adress, but pls once again try to check ur host file again and do it. If u get success then ok otherwise let me check to prepare another system step by step using diffrent ips to find out where is the problem.?
regards
