Hard to learn

I have now Storytelled new World of Darkness mortal horror/mystery game for a while, and it is supposed to turn into Werewolf: the Forsaken, as character is assumed to go first change soon in chronicle. But there is a problem.

World of Darkness core rules were easy and fast to read and learn. There was no question or problem on them. Well, basically they are just core-rules and World of Darkness is already familiar to me and I had image of dicepool system from oWoD series so it was simple to learn and ready-to-play in two evenings.

Now I have tried to read Werewolf: the Forsaken so character can go first change when ever it suits the chronicle. But there is a problem for me. I don't know am I stupid nowadays or what is wrong with me. I have read, played and game mastered dozens of systems, but why is this nearly impossible obstacle for me?

Ok, first of all, book is quite heavy. And as I know there is not wasted space for same rules WoD-core introduces, W:tF book is huge! I know White Wolf has this style of writing games full of examples and quite longish explanations on things with tons of fiction. They are nice to read and don't seem as much as an game book. But, simple things are usually explained complicated. You can read several pages of something what could have been told in few sentences more clearly.

For some reason, as I read W:tF it just doesn't make any sense to me. I get so damn frustrated for it. I have no idea why it seems to be so hard to understand. We tried to make character, or actually add Werewolf template to current campaign's character but couldn't do it! Ok, almost everything got filled but there is some unexplained gaps there.

Am I the only one, or am I just so stupid I got hard time learning Werewolf: the Forsaken? What is wrong with me or my learning? Am I too old or have I played too long same games so learning new is a bit troubling for me? Do I need a hint, what game is about so it opens to me and I get full insight of it? *sigh* I _have_ to learn it soon, or our World of Darkness campaing stays in mortal, forever.
