Hey all,

I've recently started grinding out my first Platinum trophy (PS3, of course) and I'm 94% there with Skyrim and all DLC's.
I just had a couple of points I'm hoping you might be able to help me with:

* I'm currently 1 Daedric Artifact away from Oblivion Walker. When I discovered I had to go back (due to missed artifacts, based on decisions), luckily I had a fairly old save game that allowed me to redo the quests and gain the artifacts. This save was taken from the point where you can decide to become a vampire or not. Because I just wanted to get out of Castle Volkihar ASAP, I've missed the opportunity to be turned by Harkon again - and I've now saved over this again. Soon after leaving the castle to hunt for artifacts, I had already been infected. So while I've been hunting artifacts, I've gradually been slipping into vampirism. My question is, will I now be able to complete the Vampire Mastered trophy? If so, why can I not access the vampire skill tree at the moment?

* I had completed the Companion quests much earlier on and I was a werewolf for a long time. Then I went back and finished the quest which allows you to remove the werewolf attribute - this all happened before this Dawnguard save point, mentioned above. I'm told it is possible to go back to being a werewolf, but will I be able to complete the Werewolf Mastered trophy as well?

I hope I've explained myself well enough. Any help would be greatly appreciated, thanks!
