Counter-Strike: Global Offensive cooldowns caused by pak01_001.vpk errors are non-negotiable and cannot be removed or reduced by Steam Support.
We highly recommend completing all the steps below before attempting to play Competitive to ensure you are not kicked from games moving forward.
VPK errors most often occur when third party files are added to your CS:GO install directory that are not included with the game’s default install. These files may be added when joining third party or community servers that download additional content (like sounds or images) unique to the server.
VPK errors may also be caused by hard drive corruption or faulting memory modules.
A good first step to resolve .vpk errors is to remove files from your CS:GO directory that are not included with the game’s default install, then verify your game files. To do this:
Now that you have replaced any modified files with default files, re-test the issue.
If removing third party files did not solve your vpk issues, try completely uninstalling CS:GO from your computer and re-downloading the game.
To uninstall, right click on CS:GO in your Steam Library and select ‘Manage’ > ‘Uninstall’, then re-download the game and re-test the issue.
If you continue to experience .vpk errors this likely means that one or more of your computer's memory modules is bad or failing. You can test your memory with third party programs like Memtest, available here.
Note: Please ensure that you use Memtest version 4.2 or later, as earlier versions cannot test more than 4GB of memory.
If a memory module is bad or failing, we suggest that you contact the manufacturer's warranty department for an exchange or replace the faulting module.
