NOW what? Sin puntuar aún
That's what the forum is for
Adblock Plus doesn't block *anything* by itself, it all depends on the filters you have in your list. If you filters are messed up (e.g. because some firewall software messed with downloads), you might get into this trouble. Fortunately, finding out what went wrong is easy enough - and if you ask in the forum you will get help very soon.
