Afterwards after I start to wander I get CTD's when I enter some mod added buildings and maybe others, I didn't test enough. For example http://www.fallout3nexus.com/downloads/file.php?id=3644 or the basemant of the Megaton House Basemant that has http://www.fallout3nexus.com/downloads/file.php?id=1434installed.
What could be the problem?
Here is my load order:
