You can register at https://www.soe.com/register if you want an SOE account to use their forums and probably even play the game, which you seem to have already? If your from Russia then you probably need to register at http://www.planetside2.eu/ region, the redirection page fails to do that for some reason. Its best if you use their service, in case of some issues they would be able to resolve it more efficiently. If I were you then I would rather get an opinion of someone from the official support.
