I would simply like to state my problem and ask for a fix sine I am very new to the game. I had downloaded WoW previously. The game was working for the past week. However I had to refresh my computer a while back. This somehow deleted the game but kept the launcher. Now whenever I open the game on the launcher, it gives me an error with file not found. I have re-installed the game, yet I recieve the same error. Help would be greatly appreciated

Thank you. I really appreciate that you took time out to help me
