I just recently bought Endless space emperor edition and I got three minor bugs that I would prefer non-existant. First of all every time I open endless space steam wants to modify and asks me if I want or no to autorise that thing it wants to do. Second, when i am in a game with or without people the screen would blackout from time to time, this is less of a problem because i can fix it ish, I open the task manager then re-enter the game and it is fixed until it happens again. My last issue is that for some reasons I can not be the host in multiplayer. For some weird reason it is said that i don't have the same version as my friend but we both bought the emperor edition. (we are not using any mods here)

Help? Please.
