1. Exit and restart Steam
スチームを終了して、リスタートする。
これは試し済みですね。
2. If the issue persists, exit Steam and rename the ClientRegistry.blob and restart Steam
解決しない場合は、スチームを終了した上で、ClientRegistry.blobを別の名前に変更(例:ClientRegistryOld.blob)し、スチームを再起動する。
3. If renaming the clientregistry.blob file does not resolve the issue, please exit Steam and delete everything under the Steam installation directory except Steam.exe, the ClientRegistryOld.blob, and the /SteamApps folder - this will force Steam to update when you log in
それでも解決しない場合は、Steamディレクトリ以下を一度全部削除してみる。
4. If the issue persists, please see the Verifying GCF Cache Files article for instructions to repair your game cache files.
それでも解決しない場合は、ゲームキャッシュファイルのべりファイと再構築を試みる(これはSteamディレクトリを削除すれば消えるので、気にしなくていいと思います)
5. If this issue is only happening on a third party non-Valve game, please try launching the game's .exe directly from its installation folder: C:\Program Files\Steam\SteamApps\Common\<Game Title>. You may also try other .exe's such as Launcher.exe in the game folder to see if a different error message is found.
もし特定のサードパーティのゲームにのみ起こるのであれば、C:\Program Files\Steam\SteamApps\Common\ゲーム名 のディレクトリあるexeファイルを直接起動してみる。
6. This error could also be caused by having certain Steam files set to Read Only. To resolve this:
* Exit Steam.
* Navigate to the directory where you installed Steam. (Typically C:\Program Files\ or C:\Program Files\Valve\.)
* Right-click on the Steam folder.
* Select Properties.
* Check the Read-Only checkbox and press Apply.
* Uncheck the Read-Only checkbox and press Apply.
Steamディレクトリが「読み取り専用」になっていたら、プロパティ(フォルダの右クリックで出ます)から「読み取り専用」のチェックを外す。
7. Disable all background applications, including Anti-Virus software and Firewalls.
Please see the Disabling Background Applications topic.
For information about the Windows Firewall, please view the Using a Firewall with Steam topic.
Some Anti-virus software needs to be properly configured for Steam. Please see the Antivirus software reports Steam games are malicious topic.
アンチウィルスやファイアーウォールソフトを停止してみる。
8. Double-check your router configuration to make sure that it is properly configured for Steam. If bypassing the router by connecting directly to your Cable/DSL modem allows the game to work correctly, then please consult the Using a Router with Steam topic for more detailed instructions on configuring your router.
ルーターの設定の誤り(ポートの開放など)
これはあんまり関係ないと思います。
