I recently started playing through Baldur's gate with a mega-mod for the first time. I installed the standard version of the BWP, and had no issues until midway through chapter 2, when the game became unable to save, instead asking if I would like to quit. Becasue this problem came up midway through the game, I am unsure as to how to proceed. I planned to keep my save fiels, and unistall, then reinstall BG. However with all the mods, I don't kniow how to correctly uninstall the entire program. How do I uninstall with all these modifications?

Any help would be appreciated, thanks.
