ME3 Demo not working? Whats the point.....

I don't see the point on adding demos when they don't even work. I downloaded it and when I click on the game it gets to the menu screen where press any key to continue and when I do press something It says Can't Connect To EA's Servers.. I don't get it at all.. I play BF4 and have punkbuster issues with a communicationerror and now im having EA server issues or something like that.... I dont know but to much issues involving EA and they was my favorite company.. I'm was thinking about getting origin premium or whatever its called but don't now why I should when all I have are issues.. Hope Im not the only one having issues like this..
