Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

The problem seems to occur always at the same places (one being the entrance room to lower depths in durlag`s, another is the school of necromancy, but there are countless others). Never noticed it hapenning in combat.
I am looking at a reinstallation of the game as it`s still crashing. And by crashing i am talking about a complete freeze. Can`t minimize to windows. Not even the reset button works. I have to switch of power.
Is it possible to keep the custom BGTSCC content or will i have to dl again after i de-/ reinstalled from GOG?

Go into your Userprofile/MyDocuments/NeverwinterNights2/Hak and copy the files from there if you fully uninstall the game and then re download it. However even if you uninstall it you should be prompted to keep your private files for later. I only copy the hak packs if I have to install on a completely new machine. Hope that helps
