GW is notorious for taking forever to update their games, let alone their software. There is a patch on their website but it took me forever to find it. But the patch I got last (about 2 months ago) had only the 3rd edition rules also. I'm not sure if there is a newer patch. I belive there is a link in the program group to the support site to check for a newer patch. Otherwise you'll have to search the GW site.
