PC Terraria crashes at launch.

[Mintydullworld]

Hello, months ago Terraria was working fine, perfectly fine.
Then i lost my world and char data due to an accident.
Today i tried playing Terraria again, on STEAM.
Only to be met by a game crash which provides no logs at all.
I tried to repair XNA and other FWs but to no avail.
I launched terrariaserver.exe and this is what it says.
