Warcraft 3 Crash

So, i tried to play warcraft 3 the other day and it all went good, suddenly today, when i tried to play the game bugged me at the custom games screen. 2nd when i was playing my custom maps on a daily basis it just, desynced me. 3rd when i tried restarting my Warcraft 3 it says some files require to be repaired so i clicked repair, and when i ran it it still has desyncs and bugs.

What do i do?

same issue to me. I try to install the game but it doesnt work.
After i repair, i only can play like 3 to 4 mins after that, it drops me out of the game.
