Did you say the game crashes? If it's a fatal error problem here's a way you can fix it. Just full install SOA and TOB. That way you will always just need one disk to play it. Disc 2 of Shadow of Amn. When I get the fatal error message, I exit the game, and then enter it again. Then I can continue as normal.
