Hello and thank you for your time.
After checking my system requirements I downloaded The walking dead from Steam and also the 400 days DLC. I did not see the DLC download on the steam game page wile TWD was downloading so I assume it all downloaded at the same time.
The game downloaded completely, but upon trying to open the game from either within Steam or the desktop icon it won't load. I will not get a specific error message. The gray loading box for the game to launch will either appear and immediately disappear, continue loading with no response, or the box wont appear at all. I went thru all of the steam troubleshooting options including Verifying my game cache, checking my connection with steam, and manually running secondary installers. With all results coming back with no problems detected.
Here is the "TWD_Support_data_pc" results file I saw requested from another user while browsing similar discussions. http://www.sendspace.com/filegroup/EINWmrXTVbyUtqqgUBIh4iOf0W4qW6e8
Your Help is greatly appreciated.
