So, I am getting this Fatal DirectX error (30000011) after I updated 2.3. I have been playing the game just fine before.

My desktop spec is as follow, and I have DirectX11 installed:
OS: Windows7 Ultimate 64bit SP1
Processor: AMD A6-6400K APU with Radeon HD Graphics 3.90Hz
RAM: 4GB
Video card: AMD Radeon R7 260x


I'm not sure if this is related, I have a feeling that it is, but I run the game through Steam, and I accidentally click "Verify Game Cache", and Steam made me re-download and re-installed the game. I have the game backed-up, so I recovered my files but when I try starting the game, Steam still made me re-download like half of the full game (around 4GB).
After that, the game lobby booted up, I downloaded and installed the 2.3 patch, but after I click play, the Fatal DirectX error (30000011) comes up and force quit me.

I'm not very tech savvy and hoping if someone can help me on this.
