BWS-"Please start the game, choose the language..."-Can't instal BG2:EE

Hello all,
I am having trouble using Big World Setup to mod my install of Baldur's Gate II: Enhanced Edition(GOG Version).
I am running both the "Update if Needed" and "Without Update" versions, and I have downloaded the newest version of BWS.

I get to the end, it gets ready to install the mods, and then fails with the message:
"Please start the game, choose the language you like, start and create a savegame"

Of course, I have done this, or I wouldn't be posting.

Anyway, here are the different things I have tried:
Reinstalling the game(And I have it installed to a "safe" folder. C:\Users\\Games
Importing my BG:EE savegame
Importing my BG:EE Exported Character
Starting a generic game just picking a random pre-generated character.
Saving a Quicksave
Saving a save with a custom name
Re-running BWS from scratch
Continuing my previous BWS setup
Rebooting
Changing the language to Spanish, quitting the game, restarting, and changing back to English

Running all of the steps above in a different order

I have UAC turned off, and have disabled my AntiVirus

Like I said, the game is installed into one of the locations recommended, and the save folders is in "My Documents", where it normally resides.

Am I missing something? BG1 was a piece of cake. This seemed to be going well, except it thinks that I don't have a save game.

Thanks in advance for any help!
