Freeze & Crash

Hello,

Specs:

OS: Windows 8.1 Single Language, 64bit

CPU: Intel Core i5-4210U @ 1.70GHz 2.39 GHz

RAM: 4.00 GB

GPU: NVIDIA Geforce 820M, ver: 368.22

Game Version: 1.4.0f4 (Steam) with Heart Of Gold Exp.

I did all the workarounds below but the game freezes and crashes in first tutorial while seconds after minions starts digging.

• I'm not using USB Headset while playing.
• 3D settings selected as "High-performance NVIDIA processor"
• I don't use AVG Antivirus program.

Also i did set all the graphics options to minimum, closed everything related with GPU and set resolution to 1024, but the issue persists.

Thank You,

Best Regards,
