I can't launch DA:2 on Steam or EA, it gives me the error "game license invalid". Any known fixes or is this game ruined by EA?

Good evening everyone. Would any of you recommend Dragon Age 2 this year? Please let me hear your honest thoughts and opinions, as I am aware that this game has received some negative reviews due to having been a departure from Dragon Age Origins, a game I myself have thoroughly enjoyed and still do enjoy to this day....

I originally played this game on PS3 a long long time ago and when i try to play it again, i see that this game lacks controller support. I tried to play with a keyboard and mouse, but it just feels awful. please someone tell me there's a unofficial way to play this game with a controller?...

At lvl 9 after 10 hrs and just bored out of my mind.

So my Steam account is connected to the game, I have played 2.1 hours already via Steam. Today, it doesn't wanna launch and it says network error with the following code: EC: 10005 Help?
