I own the season pass and have both expansions installed but when i go into the game I get nothing, im confused. I tried reinstalling both expansions form GoG DLC installer but still nothing. Am i doing something wrong?

Describe "I get nothing". On the title page, does it have the banners for both HoS and B&W on the bottom left saying "Installed"?

Are you at a level in the game to be able to start the expansions (32-34 or so)?
