need help with game

hey guys,

I recently bought DE as I was really enjoying aoe 2. When I launched DE I had a look at the campaigns and in those games, as well as any games I attempt to play online / against bots won't let me move my units using right click. I can make them patrol or move units using the command / hotkeys in the bottom left, but for some reason right clicking wont move units or make them do tasks i.e mine gold.

​

Does anyone have any idea what's wrong? (I've verified game cache and reinstalled the game).

I'm using Steam, and thankyou for your time.
