GoldSrc Game Error: Mod LoadBrushModel: wrong version number (0 should be 30)

http://support.steampowered.com/cgi-bin/steampowered.cfg/php/enduser/std_adp.php?p_faqid=46

This usually happens when a model or a sprite gets damaged.

You'll have to delete that offending file before you will be able to play.

You'll want to look here for the problem file (for counter-strike as an example):

C:\Program Files\Steam\SteamApps\<account>\counter-strike\cstrike

or

C:\Valve\Steam\SteamApps\<account>\counter-strike\cstrike

Since the error message tells you the file name, the fastest thing you can do is to use your operating system search to locate the file:

Start > Search > Find Files or Folders

Then select "all files and folders", select the partition or hard disk that your Steam is installed to (C: typically) and enter the name of the offending file in the "all or part of file name" area, then click on search.

If the search does NOT find the file, then this means you most likely have some corrupt data in your game cache file (GCF). To fix this, you'll have to delete the local content for that game and re-download the content again.

Before you do that, you can also try renaming your game folder temporarily and let Steam create a totally default installation, do this by exiting from Steam, then go to (using the example from above):

C:\Program Files\Steam\SteamApps\<account>\counter-strike\cstrike

and rename the counter-strike folder to this:

C:\Program Files\Steam\SteamApps\<account>\~counter-strike\cstrike

When you start up Steam and then click on Counter-Strike in the games menu, Steam will quickly create a default installation. Then you can go to the server where you were having the problem and see if you still get kicked.

If you still have the problem then you definitely have a bad cache GCF file and you'll need to re-download the content, epecially if you see any cache file error messages before you get this error.

Example: FilesOpenWithouterror D:Valve\Steam\Steam.exe Src\CacheFileFixedDirectory.cpp line 1175

((pOpenfile). flag&0x0020) = 0

To delete the local content, go to the game that is causing you problems, so:

Steam > Games > then right-click on "Counter-Strike" (for example) and select properties.

There in that properties panel is the "delete local content" button

If you are having problems with CZ or CZ Deleted scenes, then you may need to also delete the CS content or even HL content, this is the order:

CS:DS --> CZ --> CS --> HL

Each game in the sequence shown can use a resource that is in the following Game cache.

So if you have a CZ:DS problem and delete that content and it doesn't fix your problem, then delete CZ, then if that doesn't fix the problem, delete CS, and finally delete HL (you may have to D/L HL first completely to delete it).

You will need to download the game content that you delete before you can play (click on the game).
