Ok, it's about time Tech Support had a "Common Problems" page, and I'm gonna bite the bullet and make it...
Here's the current list of common problems that are covered in this topic. They'll all be posted in this first posting, with fixes being added to both the latest post, and this one... Please, make sure you check each section, and look at the "AKA"s for them all, as you problem may be listed as an "aka"Ok? Natural Selection installation issues (aka "Setup has not detected a valid Steam installation")2. Steam ID Ticket Problems (aka "Error verifying STEAM User ID ticket.")8.
Natural Selection, and 64-Bit Operating Systems (aka "Your display does not support downloadable gamma", black HUD sprites, Green scoreboard text) 3. Mismatched DLL file (aka "Your dll [cl_dlls/client.dll] differs from the server")-List ends-== Issues not covered by this post ==1.
