Configuring TheWeekinChess downloads with Megadatabase 2014 This quite a technical question, anybody who knows about the program Chessbase (12) and how it works please feel free to answer.

Recently I downloaded many PGN files from the website The Week in Chess,

I copied all of the games (over 100,000) into my current unedited version of Chessbase Megadatabase 2014, the games were installed successfully.

The problem is that when I do the 'Opening Report' and the player 'Dossier', I find that my TheWeekinChess download games are ignored, I know this because all of the TheWeekinChess downloads are games from 2014 and none of these are shown in the Opening Reports (main lines) and player Dossiers (top players).

For example, I input the moves 1.e4 c5 (Sicilian), click Opening Report and it works but the latest games are all played in 2013 even though there are games from the year 2014 in the database.

I search for a player in the Player Encyclopedia, for example: Magnus Carlsen, I click dossier and it works perfectly fine; but then again the games go no further than 2013.

Could anyone show me a way to solve this problem?
The Mega Database 2014 is in chessbase format and contains not only the games but several pre-requisite to all options proposed by Chessbase 12.
So by using pgn files, you will find the games in your database but they are not optimize for the others options.
