Ceana of the Crags:
How do I rid myself of the "enhanced" edition, to use only the original game, since it is supposedly bundled in with the ee?
Go to your account and click on Baldur's Gate: Enhanced Edition. Click on more than on Serial Keys and you will get a redeem code for the Original Saga.
This is not possible with Galaxy, you have to use a browser.
If you really want to get rid of the Enhanced Edition, you'll have to contact support and ask them to delete it from your account. Not sure they will do it though.
