Unable to Play

I"m not able to install the program through the first download file as my installer either crashes or gives me a weird garbled pop-up and then crashes again so I tried to download the Client-Portable but everytime I go to log in it gives me the message"Index was outside the bounds of the array." The game still starts to load and gets to the screen that says welcome and my character in the top left but a window keeps popping up giving my that message over and over again. Is there anyway to stop it from happening?
