Try this

Enable DEP

Data Execution Prevention (DEP) must be enabled to play on VAC secured servers. To restore DEP settings to default please follow the steps below:

Exit Steam.
Click the Start button, then 'All Programs', and 'Accessories'
Right-click on Command Prompt and click "Run as administrator..."

- Please note if you are running Windows 8 you will need to press Windows Key + X and select Command Prompt (Admin)

In the command prompt, type the following command and press Enter:

bcdedit.exe /deletevalue nx

Restart your computer.
Launch Steam and test the issue again.

Restart your modem/routers that might help, or restart your pc.

Stop your ativirus and it will stop =)

Probably your anti-virus blocking it, check your permissions. A similar problem happens when my anti-virus is running and I try to load up Rome 2.
