Please help 400 error

i have been posting about this for days, tried to contact se both by phone and through email and asked everyone i can. When i try to open launcher i get " a system error has occurred:400. http://frontier.ffxiv.com/arr_win?in...?rc_lang=en_us. " I have reinstalled game 3 times now and it keeps coming back and if not that error then it says certificates dont match and it will not connect. This has been going on for over ten hours a day the last few days and nothing i do seems to help. In the off chance this does not pop up i get d/ced after about 30-40 minutes and it says runtime error then i start the 400 dance all over again. Any suggestions would be highly appreciated.

And now i tried to uninstall and reinstall for the 4th time and it gives me that error before i can even log in to SE screen. 7 free days is not enough for this bullshit and aggravation. If its not one error its another and se doesnt even have customer support up? Totally ridiculous for a company of this size. Id take a 1017 error or a long ass que over this anyday because at least i would know the game would eventually be playable.
