If you have used a second monitor at any point, try plugging it in. Someone else had this problem, and the extension was calling the dictionary from a monitor that wasn't plugged in.

@erolx It kind of depends on your interests. Personally, I watched Avatar and I'm currently watching Inuyasha for free-flow immersion since they're a bit easier (voices clearer, story more familiar, for teens so language a little simplified). Ghibli movies are also nice, and I know some people have found Pokemon to be fun too. For kdramas, do you like crime thrillers or high school romance? Fiction or non-fiction? If you're not sure, try them all out!
