Can't Run Two Instances Of Windower?

Hi. I've scoured the internet, but can't seem to find any solutions to my problem. It seems a bit complicated.

I have absolutely no problem running vanilla Playonline and FFXI, or Windower and FFXI. However, when I am running windower and I try to open a second instance of windower to dualbox, it doesn't load. No error message, or crashing, or BSOD. It just... doesn't load. I've uninstalled, reinstalled, done just about everything I can think of.

I used to play FFXI a few months ago, and quit. I would run 2 or 3 accounts via windower on the same machine with absolutely no problems. I recently came back, and have had nothing but problems. I can't understand why. Any help would be greatly appreciated!

Are you using Win Vista/7? I had to turn off my UAC to get it to work.

I run vista x64, but I have UAC off, so that's not the problem unfortunately.

You technically don't have to turn UAC off, you just need to set it so it does not dim the screen which is the option before turning it off.

Little bit of a bump :E
