game freezing too often

[adler_1]

i installed the game 3 days ago , since yesterday the game is freezing every time i start a mission , it happens when i generate the mission single player , i get a black  blank , i log off and try again , after 3-4 attempts the mission might start and might freeze when it starts right away  , its getting worse and worse . i did not have this issue the first 2 days .
