Hi, everyone I'm trying to modify the AI package but when I click on any AI construction set stops working. If anyone knows what I can do to solve this please give me some help.

This is a very common problem. I'm still on XP, so I don't have it myself, but there is a good thread about it on the http://www.thenexusforums.com/index.php?/topic/161203-cs-crashes-when-attempting-to-edit-ai-packages/.
