Hi. I have a problem with some of the campaigns. some of them do not work at all and some of them only partly. i mean that in some campaigns i can play only 3-4 missions (arthas campaign undead version, rise of the blood elves, rise of the forsaken and so on). and in some i cant play even a single mission (like lord of clans for example). i am quite new to this site (discovered it by accident so i might write this one in wrong place). Could you help me with solving this problem? Cause most of those campaigns are really amazing and yet i cant enjoy them ;/.
