Deployed game does not run properly.

Hi, I'm new to this engine and wanted to test the Deploy feature with a game I'm making. When ran inside the engine, the game runs perfectly. But when I deploy the game to a file that can run on windows the game simply does not load. It just stays at a black screen in window mode. Does anyone have a clue why this happens? Thanks.

Could you do CTRL + ALT + I and check console tab to see if there are any errors?
