Fatal DirectX error 30000011

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.

Got it fixed by removing the whole game, then re-downloaded and re-installed it. Probably something went wrong with my backup files.
