Issues launching the launcher

Hi,

Having trouble starting the FFXIV launcher. I'm on vacation and am borrowing someone else's computer to play the game, so I copied the SquareEnix folder over and am trying to launch with ffxivboot.exe. Simply copy-pasting the folder over and launching from the boot file worked fine on my netbook so I figured everything would work even better on the computer I'm borrowing (desktop with specs more similar to my tower at home). However, the launcher only gets as far as loading a blank black screen before I get "FFXIV A REALM REBORN has stopped working" error message and I have to close the program. The error message I get from Windows 7 is:

I've tried adding ffxiv.frontier.com and the program folder to the antivirus exceptions list but to no avail. Can anyone help me out? Please let me know if there's more information I should give.

its been frustrating as hell..i just purchased another 6months sub and i can not even play game in my free time. Black launcher window or if i am lucky enough to get to put my login details in after a few moments it errors.
