I tried updating Warcraft through blizzard's own updater, and it updated strange enough. Except for the fact that I now couldn't open any maps. All maps I tried to open came up with the "Cannot Load Map Data" error. So I went through the obvious process of reinstalling Warcraft onto my Ubuntu computer. After I updated the game using the Eurobattle.net client, it came up with the same exact error. I cannot play singleplayer, multiplayer, or LAN. I am currently on 1.28.5
