Problem with signing into my Trion account on their website

I do not know where else to ask and since a lot of people are here, someone might help me. http://trionworlds.com/en/ here I cannot sign in. The website does not even load after hitting the buttom. Before I was able to enter the site after but not to login (even tried to reset my password twice). Tried 4 different browsers, delete cookies, power-cycle the router and clear dns cache and forward ports for Rift. I can login into the Rift game and play but since I cannot sign into account manager I cannot add my full version key. I contacted support and they told me that they cannot help me and some Tier 3 tech. will look for it if I check it as unresolved. However I cannot enter even into support :D I think the problem is with router, because even other laptops cannot do it. Anyone knows how to resolve this or maybe some hot-fix? I can play but I cannot enter my cd-key etc. P.S.: I have dynamic IP and I am from Czech republic. Thank you for any help advices. :)

+It is not because of Defiance, it lasts for 2 days now and other people have no problem. The guy on support told me there is nothing wrong with the account (IP ban etc.)
