first: where are you from ? arado is now only ip blocked in USA ( NA ? ) and phillipines i think .. theyve dropped it for many countries ( europe for example .. jeahjeah i know its no country .. -.- )
so just try to loginto the Arado page then youll see if you are still ip blocked .. if you are still ip blocked look into the arado senki help threat 1st page. Theres a link to the VPN client guide.
if you still dont manage to get it up and running just send me a pm and ill give you my msn-address
though i can only provide info about arado senki .. ive managed to block my DNF account .. AGAIN (dunno pw recovery's not working .. i think it shows me a different account for the pw recovery.. as if mine isnt exisiting any more or something like that )
