I've bought the 2 dlc map packs, downloaded the zip files and put on dlc folder, user/savegames/crysis2/dlc... as the instructions says. When I enter in the lobby to select a server I can see all the new maps listed but they are always greyed out and when I click to join one of them it appears this message "you do not have this user created map installed. Please visit Crymod website to download it". Please help me.

Download them in-game from the 'Download Content' section, there are three tabs there, i believe it's the 'shopping basket' one, then you re-sign in and you got em', i've done this many times.
