A Note Before Troubleshooting:
First and foremost, some users may be concerned that the client, or some of the MYSTICMS DLL files, are getting picked up by their anti-virus/anti-malware software. This is completely normal in the MSPS community.
The reason for this is that the localhost (i.e. the client) we use is unpacked to work on our own private network. As a result, this violates Nexon's digital signature, which subsequently sends an alarm to most security software. Nexon originally used Themida to protect against tampering the client, however this was cracked by some talented individuals (and subsequently, what allows us to use the client for our own server). As a result, most security software will now automatically pick-up these types of files as a false positive. To ensure your files remain untouched, please remember to add an exclusion for the entire MysticMS folder in your security software (i.e. Windows Defender). If you have any questions or concerns, please feel free to reach out via Discord!
