At first HL2 played just fine, but then suddenly I'm not able to load my saves. As soon as I click on "Load Game" it crashes back to my desktop and gives me the following message:

"FATAL ERROR: Could not acquire necessary game files because the connection to Steam servers was lost."

How do I fix it?

Download the latest drivers for your graphics card and restart Steam to get the new HL2 patch via the auto-update. You can find more advice here

The error practically answers it self.................................... connection to steam servers lost... DuH!!! reinstall steam might work.

I had big problems connecting to steam. I've got a 1MB Broadband high speed connection, but it looks to me that steam can't cope with the high demand from users. Valve has messed up on this one. A few of my friends, and I'm talking about 4 so far, have returned the game because of this. I managed to create my account and unlock the game at 3.00am (uk) on the day after release over here, this was after 4 hours of trying in the evening. Even then, for a short time afterwards it was validating game files for 20 minutes when I started it up. I am not impressed with steam. The links to steam in the game start menu don't connect either. Steam, in my opinion, will kill the single player offline gaming majority.

I've never had that problem but sometimes when i start half life 2 and get into a loaded game my computer will just restart out of no where

I also had that problem ones, but when it had restarted I got a message saying the system had recovered from a huge problem...

If you have are getting this error

FATAL ERROR: Could not acquire necessary game files because the connection to Steam servers was lost."

Block hl2 from accessing internet on the Firewall and if you have windows xp service pack 2 also block it when you get the message asking you to block hl2.

I had the same problem and that's how I fix it. It works perfectly now

doesn't work if I disable my broadband connection and try it I get the same exact message.

try installing a firewall and block hl2 from accessing internet.

I have problem with half life 2. When ever I save and reload that game everyone is frozen and no one fights back. I just shot everyone and they don't fight back. Sometime it works normal and other time this happens. What's wrong with the game?

Try opening the console and typing ai_disable 0.
Good luck

I am so nervous. my computer is coming in 3 days and I don't want half life 2 to fail.

it didnt work for me

try deleting your last couple saved games in the saved game directory. this worked for me. I made copies of them first.

Do as leigh8888, did the same and it worked for me (actually i had problems with SIN Episodes Emergence, but it uses the same platform). Well done leigh8888, thanks.
