@Vintersorg, if you have Tales of the Sword Coast installed, be sure to have the latest patch
If this doesn't help, try disabling the movies in the game by editing your baldur.ini file. Go the the section labled "Program Options" and add a line saying "Disable Movies=1" anywhere in that section. All plot advancement is done through in-game cutscenes so you will not miss any plot points by disabling the movies.
Good luck!
