Minecraft won't start from launcher

Yesterday minecraft was working fine.
Since today when I try to start from the launcher nothing happens after pressing play.
Java will show up under processes in taskmanager, but the game won't start.

My logs show only this:
[21:50:54] [Client thread/INFO]: Setting user: Tazuko
[21:50:56] [Client thread/WARN]: Skipping bad option: lastServer:
[21:50:56] [Client thread/INFO]: LWJGL Version: 2.9.4

I tried deleting the versions folder under .minecraft and deleting the Runtime folder.
Also I tried re installing Java.
