*SOLVED* Amnesia launcher not running

[TheBlastPassage]

Verify the game cache via Steam. Here's how you can do so:

1. Right-Click the game in your Steam library
2. Click 'Properties'
3. Navigate to the 'Local Files' tab
4. Click 'Verify Integrity of Game Cache'

Now give it a minute or so do validate the files and it will re-download any bad or corrupt files.

Hope this helps. Let us know if this solves your problem
