If you're experiencing HackShield or BlackCipher errors, please make sure that both are up to date. Please follow these steps:

1. Go to our Game Client and Updates page.
   
2. Scroll down to the 'Download HackShield Manual Patch' and 'Download BlackCipher Manual Patch' sections.
   
3. Follow the instructions listed in these sections.
   

Is it even possible for the client not to patch those to the current version?

Apparently the auto-update for those is buggy, and will sometimes corrupt them instead of patching.
The manual patch this notice tells you to download is actually more like a clean install. It will hopefully get updated when you run it.
