OBS game capture (window) is not showing preview and not recording too

[Bluegix]

I am new to OBS.

I am trying to record the Steam game Splinter Cell Blacklist using Game capture --> Capture specific window source.
I have tried running OBS as administrator, still it is not working. Please help.

Here is the log file. https://obsproject.com/logs/RXMgWSttAURW4zTz
