Hey,
first I'de like to say that I could not use the search function since it redirected me to an error page saying something is not right, so I'm not sure if this is a common problem.
I've installed Baldurs Gate Saga and patched it to version 5512. Then I installed Baldurs Gate 2 + Expansion and patched it (I cant remember the exact number, I simply downloaded the latest version from the bioware homepaf) and then I put the BGT-WeiDU installer into my BG2 folder and installed it (no errors occured). The game starts and except for the main menu which is a little messed up (looks like that is a resolution issue) it works fine to the point when I load a savegame. When I do i cannot talk to any more NPCs, I always get the message "You cannot initiate dialog with [NPC] because [NPC] seems busy." I've googled that and read that this could be soleved by installing the latest patch, which I already did. Any ideas how to make this work?
