Important Notice
We are currently using Season 21 Part 1–2, the newest MU version available.
Since this version is still awaiting official Microsoft certification, your system or antivirus
software may sometimes show a warning for the IGC.dll and game.exe files.
Don’t worry - our client files are 100% safe and do not contain any viruses or harmful software.
These warnings are false positives and can happen with newer game files.
To make sure the game runs without any problems, please add the
Crystal MU folder
to the exclusion list of
Windows Defender and any antivirus program you are using.
Thank you for your understanding, and we hope you enjoy your time in the game!
