Frist of all, you guys make great trainer and I always use them. But for the 1.7.7.x do you have to have dawnguard downloaded because I don't and the game always crashes when I start to play. Yes I have the 184.108.40.206 update and yes the game works fine without the trainer. Thanks for your time and keep up the great work.
the price is a little steep for a DLC but the content is fun to play and the new items and abilities are pretty cool, you get another shout that actually summons a dragon(like a conjuration spell would) and the dragon itself is undead and it uses a shout that spawns undead minions called mistmen. Also, another one of my favorite abilities in dawnguard lets you summon an undead horse via conjuration spell. the horse itself is really cool looking(skeletal with purple&white flame animations for the mane and tail) and its really convenient to be able to summon a mountable horse almost anywhere.
the story itself is not very long but it is intriguing and when its over you get a vampire follower that cant die..so if you have the extra cash, i would recommend it
