First if you downloaded the client freshly, congrats! you are alread on the latest patch!
If you did not just download the client there is a simple step to follow to get yourself patched up.
You can find the current patch located on the discord server, or you can find it in our Patch List Folder.
Just simply download the zip file, put it in your Aurora-Realms Perfect World Client, and then extract the files.
Over-write all of the new files with the old ones, and you should be good to go!
More extensive guide with pictures coming in the future, please reach out to a staff member on discord if you get stuck.
