"XKernel Error - Data in 9Dragons has changed or has failed to update successfully. Please install again", and so I did...20 times. I have turned off Windows Defender, Firewall, my antivirus but still nothing. Please help because I don't know what else to do. I spent all day today troubleshooting. I have been watching the files in my 9D folder update while the launcher installs the patches and things always stop after patch 251 installs. The XLauncher.txt log file also indicates that the launcher stops patching after 251. The weird thing is that I am having this problem with my main desktop PC but not with my laptop. Today, I was able to update to patch 252 with Windows Defender, Firewall, and the same antivirus on my LAPTOP ONLY. I also downloaded and installed everything starting from the Downloader in the RedFox website. I updated Windows and my graphics card to the latest version.
